ACTA is a secretly negotiated copyright treaty that obliges its signatories to take on many of the worst features of SOPA and PIPA. The EU is nearing ratification of it. ACTA was instigated by US trade reps under the Bush Administration, who devised and enforced its unique secrecy regime, but the Obama administration enthusiastically pursued it. This White House petition asks the administration to withdraw its support for the treaty. (Thanks, Horn55!)
