Besides the ones that they listed, I've also heard complaints about a lack of multi-monitor support and ads in the Start menu and login screen, though I believe the ads are only in certain versions of 11 (the home/personal editions, but not the more expensive company editions). I think the ads have also been limited to Microsoft products and apps from the Microsoft store - stuff like Word and Edge - but it's a really bad path that they're going down and it's only a matter of time until that becomes targeted ads to go along with their tracking and selling data.

It's going to annoy me. I keep the task bar on the bottom on my machine and on the side for remote/virtual machines
