I would personally love to use GOG for their buy-to-own model, but I’m incredibly tied into the Steam ecosystem. I just can’t live without Remote Play Together for playing with distant friends, the Workshop is incredibly convenient for modding, and free no-setup cloud sync of all my saves is a no-brainer. Gabe Newell was right when he talked about piracy being a service issue. If you provide the best service, people will keep coming back.
In that same vein, I’ll never buy another Ubisoft title as long as I live. Their crappy launcher makes it impossible to play their games on Linux.
