Napster was a joke, remember it was a software that caused a crisis... PirateBay is just a repository of links... and a ton of servers to redirect people to the right place. TPB is the same as Demonoid, isoHunt and some others.. big, structured and ready to go to trial. Napster was a single guy in need of cash, like most of the coders who develop that kind of software. TorrentBit was developped as a data-exchange protocol, and the original version now do the same as Napster, they show banners and ads...

if they decide, the whole community of torrent users who would give only 10$ to save the network would win against all the companies, because they would have a larger budget... the companies are doing it only for the money, the torrent users are doing it for the liberty...
