The information on when you are playing gives information on your job situation.
The kinds of games give insight into personality.
And so on, if you combine with data from other sources (what else happens on the IP address around the same time?) you can get quite a lot.
They definitely don’t see the VR devices as a gateway to another frontier on data collection. That’s why they paid billions for Oculus and then spent billions to sell the Quest devices at a loss.
Ignore the fact that one of basic features of the Quest is to scan your room and build a play area. Just give FB a burner account and you’re set they definitely won’t be able to tie that data together it’s not like they built their entire business around doing that.
Data, not video or pictures.
I just made a mental list of all of the items in my office room where I use Quest and the face I own a Macbook and some high end speakers/chair/desk/monitor and an iPhone is really not that interesting to anyone.
I'm way more concerned by my mobile phone or browser where I actual engage with personal information.
