The trouble is, this is really just them being honest. Within 6 months of acquiring Oculus they started pulling in data from their Oculus accounts and associating that with Facebook profiles based on email or whatever identifiers they can use. Requiring Facebook accounts is just being transparent about the fact that Facebook maintains a profile for you which crosses all of their systems whether you have accounts or not.

I hope the EU addresses the root of the issue and starts cracking down on the shadow profile stuff.
