As of October 11th you WILL submit to your Facebook overlords or forever give up enjoying VR with the Oculus technology sans FB's ridiculously awful privacy overreaches.
If I read all their legalese right, we will still be able to use current (keyword "current") Oculus technology without setting up an account but it is clear that you will need one to use future Oculus tech. However, even at that, you must sign on to the new Oculus terms of service on that date which will allow major Facebook privacy intrusions even if you do not have an account.
Bye bye, Oculus. It's been a good run, but I flat out refuse to submit to the heavy hand of Facebook.
What a damn bummer.
