If you aren't familiar with SOPA - the "Stop Online Piracy Act" or its companion in the Senate (called PIPA or Protect IP), you should be. This is legislation that would allow the US government to require Internet Service Providers block web sites without due process. Sascha Meinrath and James Losey from the New America Foundation explain the threat in Slate:

The interconnected nature of the Internet fostered the growth of online communities such as Tumblr, Twitter, and Facebook. These sites host our humdrum daily interactions and serve as a public soapbox for our political voice. Both the PROTECT IP Act and SOPA would create a national firewall by censoring the domain names of websites accused of hosting infringing copyrighted materials. This legislation would enable law enforcement to take down the entire tumblr.com domain due to something posted on a single blog. Yes, an entire, largely innocent online community could be punished for the actions of a tiny minority. If you think this scenario is unlikely, consider what happened to Mooo.com earlier this year. Back in February, the Department of Justice and Department of Homeland Security seized 10 domains during a child-porn crackdown called “Operation Protect Our Children.” Along with this group of offenders, 84,000 more entirely innocent sites were tagged with the following accusatory splash page: “Advertisement, distribution, transportation, receipt, and possession of child pornography constitute federal crimes that carry penalties for first time offenders of up to 30 years in federal prison, a $250,000 fine, forfeiture and restitution." Their only crime was guilt by association: They were all using the Mooo.com domain.

From our point of view, what is most interesting is not who is pushing this bill (Hollywood and the usual suspects that tried to kill the VCR because it would obviously destroy the movie industry) but who is not resisting.
