Your Steam games run on Linux run due to Valve's (truly excellent) work on their compatibility layer. However, that work is not exclusive to Steam. I can play my DRM-free GoG copies of big budget Windows games just fine on Linux. There's an extra step you have to invoke, but they still run superbly. Supporting DRM-free is the best we have in an increasingly hostile customer market.
I don't want to write a redo of the infamous Dropbox comment, but if you really want to go /r/datahoarders on it, you can simply have a GOG downloader running in a monthly (or whatever) cronjob.

That's funny, I don't have that issue at all. I have whatever GOG 3rd party client running on Bazzite do the downloading & updating for me, and the only game with which I had an issue was Timberborn.
That's a you problem. I keep mine backed up. GOG even makes it easy to just go grab the latest patch if you downloaded the base game years ago.
>None of my GOG games run on Linux, while most of my Steam games run on Linux. Also annoying: None of the GOG games run on a genuine Win9x either, as what you are getting is an updated version for modern Windows, not the original game.
Solvable with Wine/Proton (or a Proton fork). If you want to be lazy Heroic launcher makes it easy and even logs into GoG if you don't have them backed up locally. Heroic launcher lets you pick what you want to use to run the game whether it be Proton/Wine/Etc, this even works with Game-Porting-Toolkit on MacOS.
Absolutely not. Libraries and archives are able to keep digital copies, with limits imposed on how they may share them, not on what they're allowed to keep. They're not allowed, without a convoluted exemption, to break DRM. So if Steam disappears, we're all collectively dependent on our ability to break DRM to maintain our culture accessible. Games that use draconian authentication could simply disappear. With GOG, the only thing stopping us from having easy access is our ability to walk to our local library.
Stop spreading misinformation. Even if you're a non-techie you can add non-Steam games to Steam's launcher (my extremely tech illiterate friend just did this) and they'll run with Proton.
It comes down to a game by game basis, and it's still extremely rare (outside of recent 2025/2026 anticheat AAA title stuff) that any game would have a Linux specific/impacting patch.
