This Article explores the potential displacement of substantive copyright law in the increasingly important online environment. In 1998 Congress enacted a system of intermediary safe harbors as part of the Digital Millennium Copyright Act (“DMCA”). The Internet safe harbors and the associated system of notice-and-takedown fundamentally changed the incentives of platforms, users, and rightsholders in relation to claims of copyright infringement. These different incentives interact to yield a functional balance of copyright online that diverges markedly from the experience of copyright law in traditional media environments. More recently, private agreements between rightsholders and large commercial Internet platforms made in the shadow of those safe harbors. These “DMCA Plus” agreements relate to automatic copyright filtering systems, such as YouTube’s Content ID, that not only return platforms to their gatekeeping role, but encode that role in algorithms and software.

The normative implications of these developments are contestable. Fair use and other axioms of copyright law still nominally apply online; but in practice, the safe harbors and private agreements made in the shadow of those safe harbors are now far more important determinants of online behavior than whether that conduct is, or is not, substantively in compliance with copyright law. Substantive copyright law is not necessarily irrelevant online, but its relevance is not only indirect, but contingent. The attenuated relevance of substantive copyright law to online expression has benefits and costs that appear fundamentally incommensurable. Compared to the offline world, online platforms are typically more permissive of infringement, and more open to new and unexpected speech and new forms of cultural participation. However, speech on these platforms is also more vulnerable to over-reaching claims by rightsholders. There is no easy metric for comparing the value of non-infringing expression enabled by the safe harbors to that which has been unjustifiably suppressed by misuse of the notice-and-takedown system. Likewise, the harm that copyright infringement does to rightsholders is not easy to calculate, nor is it easy to weigh against the many benefits of the safe harbors.

DMCA-plus agreements raise additional incommensurable potential costs and benefits. Automatic copyright enforcement systems have obvious advantages for both platforms and rightsholders: they may reduce the harm of copyright infringement; they may also allow platforms to be more hospitable to certain types of user content. However, automated enforcement systems may also place an undue burden on fair use and other forms of non-infringing speech. The design of copyright enforcement robots encodes a series of policy choices made by platforms and rightsholders and, as a result, subjects online speech and cultural participation to a new layer of private ordering and private control. In the future, private interests, not public policy will determine the conditions under which users get to participate in online platforms that adopt these systems. In a world where communication and expression is policed by copyright robots, the substantive content of copyright law matters only to the extent that those with power decide that it should matter.

This version corrects a typographical error in the published version. At page 560 line 7 the word "can't" has been corrected to "can".
