Everything gets torrented. The Humble Bundle got torrented and you could buy it for five cents. Complaining about something ending up on the Pirate Bay is like complaining about used book sales; you can't say you didn't expect it.

Now, if he could prove it cost him any sales, he'd have something novel. If he could prove that fewer people paid because he didn't include DRM I would be shocked. It's mere existence on a torrent network simply says that not everyone is going to do what strangers tell them on the internet.

I can sympathize with the "downloaders" here. There is a lot of creative work that is somewhat in between things that I really like and things that I can not stand. Louis CK is one of these. I am watching his TV show most of the time, but it is nothing that I would miss if they stopped airing it or someone that I would pay to see perform live. I can understand people who download his stuff just because they have nothing better at the moment to "consume".
