I might have exaggerated a bit. I haven't really tested GOG out much because it doesn't do those things like having a Linux client I expect a consumer-centric platform to do and it caved in to the Chinese government just like everyone else.
But if the idea is that other platforms might screw you over some time down the line and this platform will have your back, I am not convinced if they entirely dismiss Linux. I know it is not practical for CDPR to develop Proton like Valve. The bare minimum they can do though is to show they have contingency plans in case Valve stops upstreaming its translation layer. Otherwise, why not stick to the platform that is too big to fail and is actually doing something useful?
If the concern is CDPR’s character, I believe their first-party games are known to be remarkably Linux friendly. CP2077 actually run best in Stadia at launch, which I believe was Linux based.
Also consider the fact that a large fraction of GOG games are painstakingly restored old games, where revenue is clearly an afterthought, they sometimes seem like a nonprofit. You can’t reasonably expect them to also add Linux support to games from an era where Linux gaming was practically nonexistent, modern Linux translation layers will most likely be completely incompatible.
And again, they have not had a client for most of their tenure, and I cannot think of anything more consumer-friendly or consistent with Linux ideology than literally letting you download the files and do what you want with them without any DRM.
