CISPA, the pending US cybersecurity bill, is a terrible law, with many of the worst features of SOPA — surveillance and domain seizures and censorship and so on. What's more, it is being supported by one of the largest Web companies in the world: Facebook. DemandProgress is asking its supporters to write to Facebook and ask them to withdraw their support.

What is Facebook thinking? They've signed on in support of CISPA — the new bill that would obliterate online privacy, give the military crazy new abilities to spy on the Internet, and potentially let ISPs block sites and cut off users accused of piracy.
