It features non-indie games, it is Windows only, and the games are saddled with DRM. There is already a very vocal discussion on the Humble Bundle Google+ thread, but it seems it is selling well."
If it happens once, it's a bug. If it happens twice, it's a feature.
If it happens more than twice, it's a design philosophy.
