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.
