The thing about PC though is that there is no exclusivity. Steam built an extremely well respected brand but if that were to turn, the moat is shallow, install a competing client and buy games from there instead. The only internal competition for consoles is digital or physical retail (Or I guess buying game codes could be pseudo-digital).

The difference is that there is no one steward. You don't need steam, there are lots of other ways to get your games. GoG, Itch.io, Windows Store, or just the developers webpage.

On PlayStation, switch, or Xbox you have only one gatekeeper, and they do not respect you
