Professor Jack Balkin has written that the advent of low-cost, immediately distributable digital content affects freedom of expression in four different ways: they make it much more important to sort and restrict access to information; it virtually removes spatial boundaries; it facilitates not only copying, but also commentary, satire and innovation; It has become a source of increasing power that makes control of the use and access of such content much more valuable to businesses26 because of digital technology that allows a much greater participation of the individual in the production and consumption of content. resulting from the advent of digital values. 28 proponents of freedom of expression generally do not challenge the right of content providers to limit the illegal reproduction of products such as DVDs and CDs. However, they argue that the same technology used to stifle piracy also offers more controls over individual consumption, which can undermine freedom of expression, like. B advertising, warnings and restrictions on the type of machine to use to consume content. In addition, critics fear that the DMCA, which adds a level of legal protection to DRM technologies, has been upheld in the most recent court decisions to prohibit the publication of information and links to programs such as DeCSS. DeCSS was an application, CSS, an encryption technology that prevents content users from copying their DVDs, reading DVDs on certain players and playing them on computers where the Linux operating system is operated.29 The Second Circuit upheld a New York District Court decision to force a site owner to remove all information links on DeCSS from its website.30 First Amender-partisan complains that the DCMA , by strengthening DRM by prohibiting circumvention activities, has prevented scientists, particularly computer security specialists, from sharing scientific research and even planning conferences in the United States.31 They argue that DMCA and DRM together could hinder the objective of intellectual property, enshrined in the Constitution itself: the advancement of science and the useful arts. Copyright owners argue that what DRM technology derives in terms of fair dealing and expression is the public by extending content to more people by discriminating against tariffs. Content providers can customize their products so that some users can pay less for more limited content, DRM, and then, expands consumer choice because: « It allows content owners to tailor their offerings to what consumers want… You have to be able to pay people for the privilege of watching movies… DRM technology allows studios to offer copies of movies that consumers want to own, and only one opportunity they have at a much lower price for those who don`t want a permanent copy, » wrote Fritz Attaway, a general manager of the Motion Picture Association.32 In other words, DRM probably improves the language, as more users can choose to purchase the work with different restrictions. has little chance of success if it is opposed to the interests of companies in protecting the value of their digital media.
