I think the rights of copyright holders to protect their interests should not infringe on our rights to be considered innocent until proven guilty. By demanding the unilateral right to take down any website without due process, the media lobbyists are infringing the rights of all internet users.
The bills seek to target any site that links to another which links to content the entertainment industry deems infringing. The cost of policing any website where users may put up anything they like would bring down even giants like Google. How much more so would they destroy the small businesses the bills pretend to defend?
