Brazil Forbids DRM On the Public Domain

nunojsilva writes "Cory Doctorow reports that the Brazilian equivalent of DMCA explicitly forbids using DRM-like techniques on works in the public domain. 'Brazil has just created the best-ever implementation of WCT [WIPO Copyright Treaty]. In Brazil's version of the law, you can break DRM without breaking the law, provided you're not also committing a copyright violation.' This means that, unlike the US, where it is illegal to break DRM, in Brazil it is illegal to break the public domain."

      Please understand a bit more before spouting this. A capitalist country with a consumer-based economy requires business protection. What's good for the company is often good for the people. Yes there are some areas in which businesses have benefitted at the expense of the individual, but there are many cases that go the opposite way. You just don't hear people complaining about them.

      To digress a bit, it's like when you learn a word for the first time, and suddenly hear it everywhere. You think it's coincidence, but it's really just that you are paying more attention to it. So someone gives you an anti-consumer example, and then you're looking for it everywhere. That's what individuals complain about, and if you talk to enough individuals, that will be all you hear. A company that pays low wages is controlling costs, and is often preventing those jobs from being lost completely as they are sent overseas. It is a balance in which the individual decides whether to work for a company, and the company tries to woo the employees while not giving so much that the cost of the good or service is overpriced.

      It is a difficult balance, and without business we have neither jobs nor products. So we must concede some points to them.

      Before someone starts on about corporate pay and lobbyists and all that, remember that the "invisible hand of the market" takes a long time to act, and it is currently swinging in the direction of shareholders having input on pay packages (so they can determine whether profits go to a single guy who makes few decisions on his own or to dividends). And more importantly, if you owned a business, wouldn't you want to have some discretion as to what to do with your money? Subject to the whims of the market of course. We need business and business needs us, and if you don't like a business stop buying and educate your friends and neighbors.

    in the US, the Digital Millennium Copyright Act prohibits all circumvention of software locks, even when they don't protect copyright

    but DMCA, in 1201(a)(1)(A), the part that prohibits playing DRMed works, says:

    No person shall circumvent a technological measure that effectively controls access to a work protected under this title.

    "This title" is Title 17; the title that creates copyright protection. If there's a public domain work that has DRM, you are allowed to defeat the DRM. You don't need to use any of the exemption clauses that come later, use any of the rules created by the librarian of congress, etc. DMCA never applies to you in the first case.

    1201(b)(1), the part that prohibits creating and transacting in tools that play DRMed works, says:

    (1) No person shall manufacture, import, offer to the public, provide, or otherwise traffic in any technology, product, service, device, component, or part thereof, that—

    (A) is primarily designed or produced for the purpose of circumventing protection afforded by a technological measure that effectively protects a right of a copyright owner under this title in a work or a portion thereof;

    (B) has only limited commercially significant purpose or use other than to circumvent protection afforded by a technological measure that effectively protects a right of a copyright owner under this title in a work or a portion thereof; or

    (C) is marketed by that person or another acting in concert with that person with that person’s knowledge for use in circumventing protection afforded by a technological measure that effectively protects a right of a copyright owner under this title in a work or a portion thereof.

    Same as above. If there are public domain DRMed works out there, you are allowed to create software that plays them and sell a billion copies of it openly. (There might be some fighting over (B) there, but .. well, we can talk about that in another thread.)

    DMCA very explicitly only applies to copyrighted works and the rights of the holders of those works. And AFAIK there hasn't been any case law that contradicts the plain reading of these parts. If you know of any, give references.

    Furthermore, Doctorow says

    for example, it would be illegal to for me to break the DRM on a Kindle to access my own novels, were they sold with Kindle DRM

    but DMCA 12(A)(3) says

    As used in this subsection—
    (A) to “circumvent a technological measure” means to descramble a scrambled work, to decrypt an encrypted work, or otherwise to avoid, bypass, remove, deactivate, or impair a technological measure, without the authority of the copyright owner

    If you are the copyright holder, just grant authorization. You (not Amazon!!!!) are the authority that the law is speaking about. You can grant it to yourself, or anyone else and under any conditions. This part of the law is utterly critical to the industries that bought this law and they can never safely repeal it without screwing themselves. If copyright holders couldn't grant permission, then there would be zero legal DVD or Blu-Ray players. Every single unit, even ones licensed by DVDCCA or whatever the Blu-Ray equivalent is, would be violations. It's implicit and hidden, but there's some legal mechanism where the movie makers grant authorization to the public to use these devices, and grant authorization to the electronics manufacturers to make them.

    RTFL, Doctorow. Oh, and if you want to fuck around with DMCA, then start thinking about what document(s) you may have signed which authorize Kindle users to read you
