You can at least make local backups of your Steam games. If a game is removed such that you can't even download it anymore, you can always just install it manually.
That's what GOG offers. And I'd advise anyone to use GOG over Steam for their principles alone. Every game you purchase through their platform is DRM free and they go to a lot of effort to preserve retro titles that would be difficult to play nowadays without a lot of tinkering. They also put no limitation on how many family members you can share your games with.
Optional DRM, but essentially on by default. Could maybe consider it malicious compliance as its so easy to bypass but still allows them to check the DRM checkbox.
