I’m not talking about billion dollar studios. I’m talking about indie devs. And Steam is 100% a monopoly regardless of how the nerds on Reddit and here feel about Valve. They are not your friends; they are a business. Moreover, they take a 30% cut and no one has ever batted an eye, not even today. Everyone went after the Apple App Store.
Their success has been to convince gamers they are friends. That’s all. Apple on the other hand garners insane antipathy from the public.
