Torrent is a sharing technology, it does not equal to sharing copyrighted matherials only. For example, if you want to share linux distro .iso file of 700 MB, it is always easier to share it thru torrent than to put it for download from 1 location.
On the other hand, MPAA, RIAA, etc. can shut down or threat to as much as they like, but those who want to share copyrighted matherials will find another way, and another... It is something that unfortunatelly cannot be stopped by shutting down 1 or 2 sites...
IMHO, until now, torrent is the best sharing technology invented, where bandwidth capacity is divided into many people who are interesed in that particular file. This is why i don't like generalisation of this matter
