In Napster it was supposed to be the user's responsibility to choose what to share, so it was just a matter of big groups of interest manipulating things. This is probably less legal than Napster.
Then again, every ISP is advertising unlimited downloads & all for everyone, the laws of some european countries even provide for a fee for blanks CD/DVDs because of the illegal downloads. Funnly things is that they probably won't take off those fees even though they continue to go after the places to get information about the downloads...
