Evil Divided Against Itself

Three adult entertainment companies are suing over illegal distribution of their copyrighted material. Immoral creativity is just as protected under the law as useful creativity. I already hate to see an awesome technology such as Bittorrent, which has revolutionized data distribution, because of copyright infringement, but how much more tainted does it look in this case. There are relevant uses out there for Bittorent technology, for example, Blizzard's update downloader.
