Some of their games have Linux support but also it seems very much that they do not care about going out of their way for Linux so it gets forgotten about for most titles
In GOG’s defense, they don’t have the resources that Steam does but it’s still pretty annoying. I have no plans to personally seriously use Windows ever again for personal use but Linux desktop usage is low and not something I’d expect a company that’s GOGs size to spend much time on yet. Steam can and does. I respect that a lot.
Companies can choose to be a part of the solution, or a part of the problem. And i can choose to spend my money on the solution. I would love some redundancy on the linux gaming store front tho, just valve seams a bit fragile. And afaik gog or anyone else can also use proton or???
