Niggles: Obviously the ones that are checking on Steam are basically buying it based on price and dont care about drm free
Not necessarily.
Price is
always a large factor in any & every buying decision.
Even those who prefer DRM-free games on GOG are probably generally not going to accept being price-gouged for the "privilege" of having a DRM-free game, and will therefore happily the buy the game on Steam instead, or otherwise, not buy the game at all on any platform if they resent this unethical, price-gouging treatment.
Just like how most GOG customers happily buy games on Steam if they think those games will never be coming to GOG.
Contrary to the sentiment in that quoted post, for most GOG customers,
preferring DRM-free games does not mean they will
insist upon buying
only DRM-free games, and especially not so at
any cost.
