Yea the Megaupload thing was nothing much to worry about, FBI took them down because they are a US based site with copywrited material openly uploaded and nothing done to stop it. On a side note, they could not stop illegal file sharing because of the way torrents work, basically you are connecting computers to each other via the internet and is basically like puting files on a usb drive and transfering them to another computer but on a much broader scale.
