A number of the biggest torrent sites are down. Others are mere shadows (e.g. kickass). I would say the law in this case is winning, perhaps because there are so many streaming options now that the demand has dried up.

What's the difference? Is it simply the size of the downloads? (Ebooks are only a few megabytes, so a single hobbyist can easily mirror the whole library these days.)
