BigTech doesn't need attestations in the passkey spec to limit freedom.
Attestations were added so that highly specific domains where attestation is required (by law, a regulator etc.) can still use the same passkey spec as everyone else without having to invent their own thing.
If there was benefit to BigTech of locking in Auth to a specific device, they'd have done it long ago - it's not difficult.
