For example, I honestly believe the Oculus founder believed the promises that you wouldn't ever need to use a FB account to use an Oculus, just given his public comments.
You can't use Oculus products now without a Facebook account?
Without a Facebook account, your Oculus headset has "limited" features. There's also been a bunch of stories on HN from people who've bricked their headset when their linked Facebook account got banned or deleted.
