Even among "privacy-conscious webizen", I take privacy seriously, I have my Nextcloud homelab, private email, use uBlock, use Wireguard on my phone, and use Linux, yet I have an Oculus Quest 2 with a Facebook account, because that kind of tracking is frankly not worrying to me. I use it to play video games. Of all the places where they can track my interest this is not one I worry about.
Amongst "normal" people Facebook is simply not a dealbreaker. My real concern with VR adoption is much more that my family simply does not see it as interesting.
