Yet most of their sales come not from GOG but from Steam.

..and I don't quite get your comment? Games sold on GOG are meant to be DRM-free. It's a requirement for them to be on GOG, not something they do out of the kindness of their heart.

If they were praising BG 3 for choosing to be on GOG as well as Steam then that'd have been a very valid point. But saying that there is no DRM associated with the game is false.

EDIT: I was wrong. There is no DRM.
