"We’ve been hearing a lot about game piracy recently, with big developers inflicting draconian online-only DRM systems on their users, and blaming their declining PC game sales entirely on piracy. I’m not questioning that piracy is common, since even honest, DRM-free, indie developers like 2DBoy report a 90% piracy rate. I am, however, questioning what this means. How much revenue are developers actually losing to piracy?"
