While you didn’t name names of what app you were using for streaming, I just got into a similar situation with my dorm and what I found worked was using wired ALVR for my streaming. Not wireless, but good, long right-angled USB-C cables don’t cost a fortune. https://github.com/alvr-org/ALVR/wiki/ALVR-wired-setup-(ALVR-over-USB)

What’s Reddit?

I think what was meant here is that it won’t run apps designed for the Oculus Quest lineup (which is based on Android), not the actual Facebook application

I assume the console / game store pays for the bandwidth, not them. No skin off their back

It’s not exactly the same, but I can vouch for StreetComplete being an incredibly good/similar game. You walk around the real world, and the app points out missing data in OpenStreetMap that you can fill in easily. You get the dopamine of a number going up, help dethrone proprietary map dominamce, and get some good excercise in in the process.
