Earlier quoted context omitted.
I always buy on Gog first because they really care about the user. No DRM, the ability to download safe copies in case some lawsuit happens and things get pulled out (e.g. like half the music in GTA San Andreas!). I understand you as a creator prefer steam but I wouldn't obey that, sorry. Also, reinforcing their market position is not in my best interest as a consumer.
I think you may have accidentally misread my post, or maybe I didn't word it carefully enough (in which case I apologize for the confusion). I don't prefer Steam. As a consumer, on principle in most cases I refuse to buy from it. Steam effectively punishes creators for not steering users towards their monopoly, and they have a ton of tools for user lock-in: Steam Input, Steam Workshop, etc... They may not be as egreg…
The biggest example I'd like to call out here is that I recently moved from Nintendo Switch to Steam Deck. I was astonished by how much the Steam Deck is just a Linux computer. And I was fully able to install Heroic Launcher, which is compatible with GOG, and install all my GOG games on my Steam Deck and have them work just fine. This is light years away from where Apple is. If Apple had anything remotely like this, I would be a customer quite quickly. But it's the lack of freedom and choice that I find so objectionable.
