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.
Supposedly, they are taking government funds for help (like refugees) and polluting the pureness of the culture.
In reality they are making locals even richer by taking shit jobs at low salary, and enriching the culture (like food!)
