Interesting wordsmithing. Why did you ignore Xbox?

Oh yeah, Xbox client ships with windows lol . And Apple has made it increasingly difficult to install apps outside of their store

Furthermore, you’ve narrowed down gaming to a very narrow definition. Nobody is stopping PlayStation or Nintendo selling games on PC. Whether or not you like it though, they are selling games, and they do compete with steam

Or are you genuinely arguing that Xbox, PlayStation and Nintendo aren’t competing?
