I understand what you're saying, but with Facebook it's different, because it's tied to your real identity, which changes the context a lot compared to other services.
In my case, because of that, getting a Facebook account is hard, if not impossible, because those "real identity" checks are obscure: I attempted twice to sign up for work-related reasons, and I failed both times despite providing IDs and pestering support.
I have literally NO idea why I cannot have a FB account.
However, even if I could, I hate Facebook so goddamn much that if this was my only option I would rather not use VR altogether.
And I love my Oculus Rift, especially for game development.
I am royally pissed off, and I will gladly go forward with a class action lawsuit.
