I did not downvote you and I genuinely just saw your post now, chill your bits. Some of us have a job or a life beyond refreshing social media constantly (and I'm already pretty bad on that front).
So to your question, I didn't say "force you to log in before they work", I said "ask for a login". Which my ASUS display in fact does to deliver updates and control lighting. In fairness, their dumb app also covers the keyboard, mouse and motherboard RGB, but account login it has. So does my Logitech mouse, by the way. My other Alienware monitor is interesting, because it doesn't have a login, but it does ask to collect your data, including it scrubbing your games library and constantly monitoring your controller with no opt-out for some reason. I think I would have preferred a login. Still better than Armoury Crate, though.
And of course that assumes we're only talking about PC monitors. Every single one of my TVs requests a login as part of the first time setup process, whether you use them stand-alone or as a PC output. The trophy to most annoying spyware on that front has to go to LG, whose WebOS device allows me to log out after creating an account if I want, but then it will stop updating some of my apps, so each time Max decides to change its name or Disney wants to change the background on its Disney Plus app I have to manually log in, update, then log out again. Fun!
