It's become something of a truism that they can't ever stop sharing - that it's just a game of whack-a-mole. But there's no question that torrenting has become harder - and a bit more dangerous. It's harder finding a working torrent search site, and it's harder finding a viable torrent.
The MPAA gang probably aren't that interested in stopping every last torrent, closing off every last proxy, disabling every last TOR browser. As long as it's a bit harder than it used to be (open site, enter search term, start download), and as long as the legit channels get better (and they are, slowly), chances are that file-sharing will be one of those things we have to explain to children, that we used to do in the olden days.
