Edit: Yo, I'm not saying this is gonna happen. I just want to say that Windew's UX sucks ass.
So steam has had 20 years to enshitify, in that time they have always remained a privately held company and have made choices to ensure long term growth. I imagine at some point (like after gaben hands over control) they could go public and obtain their very own collection of worthless bloodsucking vampires, but i imagine that would be quite awhile, and hopefully by then they will have removed windows death grip from gamers throats.
Enshittifying is usually the process of monetizing a platform that is running at a loss to build a user base. Steam is not running at a loss, they are making a killing as is.
