At last count wasn't something like half of all internet traffic in the USA all P2P traffic. The MAfiaa's need to understand that times have changed. People want to get there music/movies in different ways and use it the way they want to use it. Sometimes you don't want the movie with 2 million hours of extra crap footage, or the latest wonderteen make your ears bleed crap song.
I can see it now, half of the US gets banned from the net for warning letters.
