I'm 100% in agreement that a Facebook account shouldn't be required to use an Oculus.
But to continue on your tangent, I'm curious what people expect Facebook to do if they don't collect some amount of identifying information. On one hand they have a huge problem with bots, fake likes, and misinformation accounts, and on the other hand people complain about and avoid the steps they take to prevent those accounts. So, any ideas on the solution?
