This post aims to be an objective analysis of SOPA, as they stand at the time of writing. I will attempt to update this as and if the law progress. Obviously I have no familiarity with US lawmaking, which may be particularly evident in this post.
The Stop Online Piracy Act (SOPA) and Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act (Protect-IP Act or PIPA) were introduced into the US House of Representatives and Senate respectively in the summer of 2011. They cover substantially the same material, and only SOPA will be analysed here. As their titles suggest, they are both aimed at reducing or restricting the online infringement of copyright, by targeting certain websites both directly, indirectly and through their financing.
