An update to the Wolfire Games Blog reflects on piracy of the Humble Indie Bundle, the pay-what-you-choose bundle of independent games (thanks Joao). By their simple estimate, about 25% of the downloads of the bundle from their site are pirated, not even counting BitTorrent and other external sources. They reflect on the thinking that might cause users to pirate the games rather than contribute a penny to be a legitimate customer, and while they are not happy about the situation, they also admit they are not really planning on doing much to curtail this:

There is probably a way to get the best of both worlds, but it's not my area of expertise. Making the download experience worse for generous contributors in the name of punishing pirates doesn't really fit with the spirit of the bundle. When considering any kind of DRM, we have to ask ourselves, "How many legitimate users is it ok to inconvenience in order to reduce piracy?" The answer should be none.
