I almost always used the windows version on Linux too. Personally I install via the exe installer like a caveman lol, but you can add your GOG account on Lutris and other programs to make it easier. Just found out about Minigalaxy, looks nice might try it.

It ain't great that there isn't an official Gog Galaxy for Linux. But we're still super grateful for the lack of DRM.

I haven't. Works great with Heroic Games Launcher.

Just use Heroic. A native linux client would just be worse and proprietary.

That's an odd thing to get hung up on. I buy more from Steam because the client is way nicer on Linux and they actually release interesting features for it. I could buy from GOG through Heroic, but they why should I expect them to properly support me on Linux when they don't even bother to explicitly support Heroic (they do profit share, but that's not quite the same), much less port Galaxy?

I personally don't see piracy (i.e. boycotting) as a reasonable reaction here. It sounds more like you're looking to justify piracy a deal looking for an excuse.

I'll leave it there, but that's my read here.
