Really? Really Sony BMG? After over 30 million views you just now decided to make YouTube pull Rick Astley's "Never Gonna Give You Up" for a terms of use violation? If you were going to try to stop rickrolling, couldn't you have at least done it a couple years ago?
Do you know what's going to happen now? People are going to be rickrolling other people as much as possible using illicit streams as a protest all day. Thanks, assholes. Thanks.
Update: Via Ken Fisher, here's why Sony BMG pulled the original video.
Update 2: It's back, it was all a big mistake. [Neowin]
