No way, no how, no third-party DRM!
This group opposes games that are using additional DRM software. These violate the basic Steam principle that games remain in the user account even after uninstalling them, only a click away.
This group in no way endorses piracy of any kind.
The Valve policy is now to disclose DRM usage on relevant store pages. However, the information provided is not always consistent with what is included with the games.
