That's very paranoid. Occam's razor, my friend. They were probably going to do this anyway with timing being a coincidence. People give the US government too much credit for planning devious things. Most of it is a lot of fuck-ups and political favors. Nothing more. I sincerely doubt the Feds did this as so to give the finger to protesters. They've been doing this long before SOPA was introduced and will continue too. SOPA just codifies the status quo so that the chances of anyone getting in trouble for shutting sites down becomes nil.
