Just make a fake FB account exclusively for this purpose. If you're forced to use a FB account at least don't link it to your actual profile. I have a separate fake FB account for every service that requires FB.
This is great advice until Facebook blocks your secondary accounts, which might end up costing you access to any data/saves/content tied to your oculus or whatever linked services. Just look at how much destruction Google causes people and businesses by closing down all of their accounts for even accidental associations with flagged accounts.
Until they make you download the FB app to use it, and then they get access to everything you do on your phone and follow you around the internet. So sacrifice your privacy, or sacrifice the Oculus. I know which one I'm going to choose.
Fine, they can have the number of the burner phone that spends its time in my desk drawer with a dead battery, and is used for nothing but jumping through privacy-invading hoops.
Interesting. Just downloaded the app and the first thing it asks for is my number (which makes sense, I suppose). Without digging too deep -- is there cost associated here?
