Recent developments in the the fields of copyright and the field of responsibility of the the hosting provider are more than alarming. They are outright dangerous.
Recent court verdict in Italy against Google, semi legal attempt to close down Russian torrent tracker Torrents.ru and several other cases show that we are at a very dangerous path that can seriously damage our cultural and technologic progress. Furthermore, copyright laws, quickly becoming into a weapon to ram anyone or anything, like business or political opponents.
If drastic moves will not be taken soon, we will see more such cases and they will be more and more dangerous and ugly.
