Justia guest columnist and Temple law professor David Post offers a clear, detailed explanation of SOPA (and similar bills), and the reasons why they eventually failed—and, Post argues, should have failed. As Post explains, SOPA’s aim was to reduce or eliminate access to websites that are dedicated to infringing activities, and are operating outside of U.S. borders. (Such offshore websites offer, for example, copyrighted music or movies for download, or sell knockoffs of trademarked products, all without proper authorization from the rights holder.) Post explains why SOPA failed, noting that it would have done damage to the technical infrastructure of the Internet. For that, and other reasons—including SOPA’s disregard for due process when it comes to foreigners and their sites—Post argues that SOPA’s plan for Internet law enforcement, based on seizing and sanctioning domain names, is deeply flawed.
