It’s been posted before, but just a reminder everyone: If you are concerned about the mandatory Facebook account requirements, vote on it over on the official Quest Oculus uservoice channel!
Upvoting reddit posts about it may feel good, but this is their official user feedback system! You don’t even need an account, just your email to vote. Blowing this up doesn’t guarantee any changes, but it makes the case that ‘it’s not a big issue’ much harder for them to argue internally.
(also one for removing FB required social features for Rift)
