The worst part of the Facebook/Oculus integration is that there's no way to log out--you can't even revoke the login remotely via the Facebook settings page which can do that for any other device--so anyone who has access to your headset has access to your Facebook account and your Messenger history, forever.
With Quest 1, which had a separate account system, I would frequently show off the headset by letting people try it on. With Quest 2, anyone who tries it on would have full access to my Facebook account and Messenger history, so I can't do that. And no, they don't give you any sort of warning about this, you have to figure it out yourself.
(I reported this to their bug bounty program on October 26. The submission was rejected as a duplicate. I rechecked today and it was still not fixed.)
