some people are just dicks. people doing that don't help anyone, it just shows that some people are happy to support DRM.
I don't see how pirating a non-DRM game somehow equates to that person "supporting" DRM.
I wouldn't be surprised if people working for rival companies like EA did it to try scupper GOG, it's just senseless otherwise to make special "gog editions" of downloads when just about all old games are available illegally already.
Do you really believe this? That there's some huge conspiracy by the big game publishers (e.g. EA) where they are committing extremely illegal acts just to bolster the argument for including DRM on games (or something)? I don't buy it, especially in this age of anonymous ethics reporting and the ease by which an employee could leak incriminating documents (e.g. Wikileaks).
