I love Steam, Valve and Proton, and what they've done for Linux gaming, but nothing will make me compromise on DRM. To me, ending DRM is just as important as supporting free operating systems, so unfortunately no amount of good will gives Valve a free pass in my eyes.

So I've started buying games from DRM-free platforms like GoG and adding them to Steam as non-Steam games. Same compatibility and no need to use an external tool to maintain Wine/Proton prefixes. With the boatloads of money Valve makes from Steam, they probably won't miss me too much.
