Everything that has a store requires an account.

• Steam - you need Steam account (also applies to Valve Index then)
• iPhone - you need Apple account
• Android phones - you need Google account
• Oculus before - you needed an Oculus account

The short time during which they required a Facebook account (i.e. an account linked to an unrelated service) was a fuck-up, but they have since reversed that decision. Now it’s just a separate standalone VR-related account.

If anything, that is still better than the current Google/Apple situation with their accounts, which link together a bunch of unrelated services (photos, email, payments, storage sync, etc.) in an inseparable way.

Oculus. No way they would have otherwise had the money to make cheap standalone VR headsets like the Quest.
