Right but to me that seems like a good thing. In fact, don't you think it is a little bit risky to have all your games in the steam library, protected by DRM? What if steam stops being around? Having different stores also forces these publishers to be more creative to get people on their platforms, see the weekly free games in the Epic Games Launcher. If there was no competition, there wouldn't be the possibility to buy DRM free games on GOG for example.
