There is nothing wrong with allowing people to optionally choose to buy
copy-protection products that they like.


What is wrong is when people who would like products that simply record
bits, or audio, or video, without any copy protection, can’t find any,
because they have been driven off the market. By restrictive laws like the
Audio Home Recording Act, which killed the DAT market. By
“anti-circumvention” laws like the Digital Millennium Copyright Act, which
EFF is now litigating. By Federal agency actions, like the FCC deciding a
month ago that it will be illegal to offer citizens the capability to
record HDTV programs, even if the citizens have the legal right to. By
private agreements among major companies, such as SDMI and CPRM (that later
end up being “submitted” as fait accompli to accredited standards
committees, requiring an effort by the affected public to derail them). By
private agreements behind the laws and standards, such as the unwritten
agreement that DAT and MiniDisc recorders will treat analog inputs as if
they contained copyrighted materials which the user has no rights in. (My
recording of my brother’s wedding is uncopyable, because my MiniDisc decks
act as if I and my brother don’t own the copyright on it.)

Pioneer New Media Technologies, who builds the recently announced
recordable DVD drive for Apple, says “The major consumer applications for
recordable DVD will be home movie editing and storage and digital photo
storage”. They carefully don’t say “time-shifting TV programs, or
recording streaming Internet videos”, because the manufacturers and the
distribution companies are in cahoots to make sure that that capability
NEVER REACHES THE MARKET. Even though it’s 100% legal to do so, under the
Supreme Court’s _Betamax_ decision. Streambox built software that let
people record RealVideo streams on their hard disks; they were sued by Real
under the DMCA, and took it off the market. According to Nomura Securities,
DVD Recorder sales will exceed VCR sales in 2004 or 2005, and also exceed
DVD Player-only sales by 2005.
(http://www.kipinet.com/tdb/1000/10tdb04.htm) So by 2010 or so, few
consumers will have access to a recorder that will let them save a copy of
a TV program, or time-shift one, or let the kids watch it in the back of
the car. Is anyone commenting on that social paradigm shift? Do we think
it’s good or bad? Do we get any say about it at all?

Instead, consumers will have to pay movie/TV companies over and over for
the privilege of time-shifting or space-shifting. Even if they have
purchased the movie, and it’s stored at home on their own eqiupment, and
they have high bandwidth access to it from wherever they are. This concept
is called “pay per use”. It can’t compete with “You have the right to
record a copy of what you have the right to see”. These companies can’t
eliminate that right legally, because it would violate too many of the
fundamentals of our society, so they are restricting the technology so you
can’t EXERCISE that right. In the process they ARE violating the
fundamentals on which a stable and just society is based. But as long as
society survives until after they’re dead, they don’t seem to care about
its long-term stability.

What is wrong is when companies who make copy-protecting products don’t
disclose the restrictions to the consumers. Like Apple’s recent
happy-happy web pages on their new DVD-writing drive, announced this month
(http://www.apple.com/idvd/). It’s full of glowing info about how you can
write DVDs based on your own DV movie recordings, etc. What it quietly
neglects to say is that you can’t use it to copy or time-shift or record
any audio or video copyrighted by major companies. Even if you have the
legal right to do so, the technology will prevent you. They don’t say that
you can’t use it to mix and match video tracks from various artists, the
way your CD burner will. It doesn’t say that you can’t copy-protect your
OWN disks that it burns; that’s a right the big manufacturers have reserved
to themselves. They’re not selling you a DVD-Authoring drive, which is for
“professional use only”. They’re selling you a DVD-General drive, which
cannot record the key-blocks needed to copy-protect your OWN recordings,
nor can a DVD-General disc be used as a master to press your own DVDs in
quantity. These distinctions are not even glossed over; they are simply
ignored, not mentioned, invisible until after you buy the product.

It isn’t just Apple who is misleading the consumer; it’s epidemic. Sony
portable mini-disc recorders only come with digital INPUT jacks, never
digital OUTPUTS. Sound checks in — but only checks out in low-quality
analog formats. Intel touts the wonders of their TCPA (Trusted Computing
Platform Architecture). You have to read between the lines to discover
that it exists solely to spy on how you use your PC, so that any random
third party across the Internet can decide whether to “trust” you — the
owner. TCPA isn’t about reporting to YOU whether you can trust your own PC
(e.g. whether it has a virus), it doesn’t include that function. It exists
to report to record companies about whether you have installed any software
that lets you make copies of MP3s, or any free software to circumvent
whatever feeble copy-protection system the record company uses. Intel is
pushing HDCP (High Definition Content Protection) which is high speed
hardware encryption that runs only on the cable between the computer and
its CRT or LCD monitor. The only signal being encrypted is the one that
the user is sitting there watching, so why is it encrypted? So that the
user can’t record what they can view! If the cable is tampered with, the
video chip degrades the signal to “analog VCR quality”.

Intel is also pushing SDMI and CPRM (Content Protection for Recordable
Media) which would turn your own storage media (disk drives, flash ram, zip
disks, etc) into co-conspirators with movie and record companies, to deny
you (the owner of the computer and the media) the ability to store things
on those media and get them back later. Instead some of the stored items
would only come back with restrictions wired into the extraction software
— restrictions that are not under the control of the equipment owner, or
of the law, but are matters of contract between the movie/record companies
and the equipment/software makers. Such as, “you can’t record copyrighted
music on unencrypted media”. If you try to record a song off the FM radio
onto a CPRM audio recorder, it will refuse to record or play it, because
it’s watermarked but not encrypted. Even when recording your own brand-new
original audio, the default settings for analog recordings are that they
can never be copied, nor ever copied in higher fidelity than CD’s, and that
only one copy can be made even if copying is ever authorized (if the other
restrictions are somehow bypassed). Intel and IBM don’t tell you these
things; you have to get to Page 11 of Exhibit B-1, “CPPM Compliance Rules
for DVD-Audio” on page 45 of the 70-page “Interim CPRM/CPPM Adopters
Agreement”, available only after you fill out intrusive personal questions
after following the link from http://www.dvdcca.org/4centity/ . All Intel
tells you that CPPM will “give consumers access to more music”
(http://www.intel.com/pressroom/archive/releases/aw032300.htm). Lying to
your customers to mislead them into buying your products is wrong.
What is wrong is when scientific researchers are unable to study the field
or to publish their findings. Professor Ed Felten of Princeton studied the
SDMI “watermarking” systems in some detail, as part of a public study
deliberately permitted by the secretive SDMI committee, so they could
determine whether the public could crack their chosen schemes. (SDMI would
not allow EFF to join its deliberations, saying that we had no legitimate
interest in the proceedings because we weren’t a music company or a
manufacturer. There are no consumer or civil rights representatives in the
SDMI consortium.) Prof. Felten was in the New York Times last week, saying
the SDMI people and Princeton’s lawyers are now telling him that he can’t
release his promised details on what was wrong with these watermarking
systems, because of the Digital Millennium Copyright Act. It’s OK to tell
the SDMI companies how easy it is to break their scheme, but it isn’t OK to
tell the public or other scientific researchers.

What is wrong is when competitors are unable to build competing devices or
software, vying for the favor of the consumers in the free market. Instead
those devices are banned or threatened, and that software is censored and
driven underground. Such as the open-source DeCSS and LiViD DVD player
programs. Such as DVD players worldwide that can play American “Region 1”
DVDs. EFF spent more than a million dollars last year in defending the
publisher of a security magazine, and a Norwegian teenager, from movie
industry attempts to have them censored and jailed, respectively, for
publishing and writing competing software that lets DVDs be played or
copied but does not follow the restrictive contracts that the movie studios
imposed on most players. The movie studios spent $4 million on prosecuting
the New York case alone. Few or no manufacturers are willing to put
ordinary digital audio recorders on the market — you see lots of MP3
*players* but where are the stereo MP3 *recorders*? They’ve been chilled
into nonexistence by the threat of lawsuits. The ones that claim to
record, record only “voice quality monaural”.

What is wrong is when the controls that are enacted to protect the rights
reserved under copyright are used for other purposes. Not to protect the
existing rights, but to create new rights at the whim of the copyright
holder. Movie companies insisted on a “region coding” system for DVDs,
because they would make less money if DVD movies were actually tradable
worldwide under existing free-trade laws. (They couldn’t charge high
theatre ticket prices if the same movie was simultaneously available on
DVDs, and they couldn’t combine the ad campaigns of the theatres and the
DVDs if they waited a long time between releasing it to theatres and
releasing it to DVDs.) This system results in the situation where a
consumer can buy a DVD player legally, buy a DVD legally, and put the two
together, and the movie won’t play. The user has every legal right to view
the movie, but it won’t play, because if it did, movie companies might make
less money. Similar controls exist in DVDs to prevent people from
fast-forwarding past the ads or those nonsensical “FBI Warnings”.
Microsoft built some deliberately incompatible protocols into Windows 2000
so that competing Unix machines could not be used as DNS servers in some
circumstances. Microsoft released a specification but only under an
encrypted file format that claimed to require that readers agree not to use
the information to compete with them. When someone decrypted the trivial
encryption WITHOUT agreeing to the terms, Microsoft threatened to use the
DMCA to sue Slashdot, the popular free-software news web site, who
published the results. (Luckily for us, Slashdot has a backbone and said
“go ahead, we’ll defend that suit” and Microsoft chickened out.) Copyright
doesn’t grant the right to prevent competition, or to restrict global trade
— but somehow the legislation that was enacted to protect copyrights is
being used to do just those things.

What is wrong is when social policy is created in smoke-filled back rooms,
between movie/record company executives and computer company executives,
not by open public discussion, by legislatures, and by courts. The CPRM
specification, for example, allows a distributor of a bag of bits (who has
access to software with this capability) to decide that future recipients
will not be permitted to make copies of that bag of bits. Or that two
copies are permitted, but not three. This policy is not legally
enforceable, it was not created by law. The law says something different.
But the policy will be enforced by equipment built by all the major
manufacturers, because they will be sued by the movie/record companies if
they dare to build inter-operating equipment that lets consumers make THREE
copies, or copies limited only by their legal rights. Is it unexpected
that such back-room policies end up favoring the parties who were in the
room, at the expense of consumers and the public?

What is wrong is when the balance between the rights of creators and the
rights of freedom of speech and the press is lost. Because any increase in
the rights of creators is a DECREASE in the public’s right of free speech
and publication. Whenever copyrights are extended, the public domain
shrinks. The right of criticism, the right to dispute someone else’s
rendition of the truth, is damaged. The First Amendment gives an almost
absolute right to publish; the Copyright clause gives a limited right to
prevent publication by others. Any expansion of the right to prevent
publication diminishes the right to publish. For example, nothing that was
created after 1910 has entered the public domain, because as the years went
by, the term of copyright kept getting extended. But the copy-rights
created by technological restrictions are not even designed to end. There
is nothing in the SDMI or CPRM spec that says, “After 2100 you will be
permitted to copy the movies from 1910”.

What is wrong is that a tiny tail of “copyright protection” is wagging the
big dog of communications among humans. As Andy Odlyzko pointed out,
(http://www.research.att.com/~amo/doc/eworld.html, see “Content is not
king” and “The history of communications and its implications for the
Internet”), “The annual movie theater ticket sales in the U.S. are well
under $10 billion. The telephone industry collects that much money every
two weeks!” Distorting the law and the technology of human communication
and computing, in order to protect the interests of copyright holders,
makes the world poorer overall. Even if it didn’t violate fundamental
policies for the long-term stability of societies, it would be the wrong
economic decision.

What is wrong is that we have invented the technology to eliminate
scarcity, but we are deliberately throwing it away to benefit those who
profit from scarcity. We now have the means to duplicate any kind of
information that can be compactly represented in digital media. We can
replicate it worldwide, to billions of people, for very low costs,
affordable by individuals. We are working hard on technologies that will
permit other sorts of resources to be duplicated this easily, including
arbitrary physical objects (“nanotechnology”; see
http://www.foresight.org). The progress of science, technology, and free
markets have produced an end to many kinds of scarcity. A hundred years
ago, more than 99% of Americans were still using outhouses, and one out of
every ten children died in infancy. Now even the poorest Americans have
cars, television, telephones, heat, clean water, sanitary sewers — things
that the richest millionaires of 1900 could not buy. These technologies
promise an end to physical want in the near future.

We should be rejoicing in mutually creating a heaven on earth! Instead,
those crabbed souls who make their living from perpetuating scarcity are
sneaking around, convincing co-conspirators to chain our cheap duplication
technology so that it WON’T make copies — at least not of the kind of
goods THEY want to sell us. This is the worst sort of economic
protectionism — beggaring your own society for the benefit of an
inefficient local industry. The record and movie distribution companies
are careful not to point this out to us, but that is what is happening.
If by 2030 we have invented a matter duplicator that’s as cheap as copying
a CD today, will we outlaw it and drive it underground? So that farmers
can make a living keeping food expensive, so that furniture makers can make
a living preventing people from having beds and chairs that would cost a
dollar to duplicate, so that builders won’t be reduced to poverty because a
comfortable house can be duplicated for a few hundred dollars? Yes, such
developments would cause economic dislocations for sure. But should we
drive them underground and keep the world impoverished to save these
peoples’ jobs? And would they really stay underground, or would the
natural advantages of the technology cause the “underground” to rapidly
overtake the rest of society?

I think we should embrace the era of plenty and work out how to mutually
live in it. I think we should work on understanding how people can make a
living by creating new things and providing services, rather than by
restricting the duplication of existing things. That’s what I’ve
personally spent ten years doing, founding a successful free software
support company. That company, Cygnus Solutions, annually invests more
than $10 million into writing software, giving it away freely, and letting
anyone modify or duplicate it. It funds that by collecting more than $25
million from customers, who benefit from having that software exist and be
reliable and widespread. The company is now part of Red Hat, Inc — which
also makes its living by empowering its customers without restricting the
duplication of its work. It’s no coincidence that the open source, free
software, and Linux communities are among the first to become alarmed at
copy protection. They are actively making their livings or hobbies out of
eliminating scarcity and increasing freedom in the operating system and
application software markets. They see the real improvement in the world
that results — and the ugly reactions of the monopolistic and
oligopolistic forces that such efforts obsolete.

Converting the whole world to operate without scarcity is a huge task. Such
a large economic shift would take decades to spread through the entire
world economy, making billions of new winners and new losers. We will be
extremely lucky if by 2030 we are *prepared* to end scarcity without
massive social turmoil, including riots, civil unrest, and world war. If
we are to find a peaceful path to an era of plenty, we should be starting
HERE AND NOW, transforming the industries we have already eliminated
scarcity in — text, audio, and video. Companies that can’t adjust should
disappear and be replaced by those who can. As these whole industries
learn how to exist and thrive without creating artificial scarcity, they
will provide models and expertise for other industries, which will need to
change when their own inefficient production is replaced by efficient
duplication ten or fifteen years from now. Relying on copy-protection now
would send us in exactly the wrong direction! Copy protection pretends
that the law and some fancy footwork with industrial cartels can maintain
our current economic structures, in the face of a hurricane of positive
technological change that is picking them up and sending them whirling like
so many autumn leaves.

This may be a longer discussion than you wanted, Ron, but as you can see, I
think there are a lot of things wrong with how copy protection technologies
are being foisted on an unsuspecting public. I’d like to hear from you a
similar discussion. Being devil’s advocate for a moment, why should
self-interested companies be permitted to shift the balance of fundamental
liberties, risking free expression, free markets, scientific progress,
consumer rights, societal stability, and the end of physical and
informational want? Because somebody might be able to steal a song? That
seems a rather flimsy excuse. I await your response.

John —
Great essay… thanks for replying at such length!
I’m going to decline your (perhaps rhetorical) invitation to provide a
devils-advocate counter-argument, because I’m not the right person to do
so; I am far too liberal in my own views to be a fair representative of the
“dark side”. In any case, I was asking more for an education (which you
