Edit: Yo, I'm not saying this is gonna happen. I just want to say that Windew's UX sucks ass.
There are also people using Steam who would very much rather not use Steam but need to because it is the only way to use given software. So many Steam exclusives.
I remember a time when I wanted to play Portal and the only thing in the physical box was a code and a Steam installer.
Just because it is a monopoly you like doesn't mean it isn't a monopoly.
Your argument that Steam is a monopoly involves you purchasing a game from somewhere other than Steam?
Yes, buying from somewhere else and still being forced to install Steam just to be able to play it.
So your issue is with launchers then, because that does not describe a monopoly.
