According to the Congressional Budget Office, the PROTECT-IP/Stop Online Piracy Act (PIPA/SOPA) bill currently gaining momentum in Congress will cost taxpayers $47 million a year. In this video above from Fight for the Future, other major drawbacks beyond costs of PIPA/SOPA are enumerated, including empowering government and corporations with the ability to censor the Internet under the guise of protecting creative works.
Under the bill, sharing a video with any copyrighted material could be considered illegal copyright infringement, subjecting the site to a shutdown without any recourse to the site owner.
