This is not new, but it’s well sourced and easily digestible for most people. The issue is that Valve has de facto monopoly and when Epic Games (even selfishly) tried to address that issue gamers went for their throat instead of cheering.

There are small storefronts that exist in the background, but they are either indie only like itch.io, Game Jolt or run by a publisher with primarily their catalog like GOG, Origin, Uplay (or whatever it’s called now), Battle.net, etc. And even then many of them eventually become available on Steam because that’s what gamers ask for. People are too stupid to help themselves, so unless some regulations force a change, we are stuck with this.
