> I want a OS, not an entertainment center

Exactomundo! I'm a software developer, not a florist. I don't care about all those animations, transitions, dancing emojis, styled sliding notifications, windings and dingleberries. If I want to rebind a fucking key I should be able to. If I want to replace the entire desktop with a tiling manager of my choosing — that should be possible. And definitely, absolutely, in no way, should just about any kind of app, especially a web-browser, be shoved in my face. "Edge is not that bad", they would say. And would be completely missing the whole point.
