Fwiw, GOG has no DRM for their titles (its own niche space, not competition). Not sure if they charge 30% too, but even in such case they’re giving you more because of the lack of DRM.
Steam is quite virtuous, they gave us Proton. But is far from being based.
GOG has no DRM, but they also don’t offer the same kind of services, like workshop, updates, cloud sync, etc.
Not trying to say they’re worse or anything, I love GOG, but it’s really kind of comparing apples to oranges here.
