On the other hand, many games (by number at least) on Steam do not have any DRM and you can back up the installed files as easily as you can back up a GOG installer. Many more games only need Steamworks which is easily bypassed.
Meanwhile Valve is actively working on making Linux gaming better (which I care about) while GOG/CDPR can't even be bothered to port their own games or their store client.
GOG for buying stuff DRM free, and Game Pass for renting it cheaply if you don't care to own it
