It could be done in a way that Apple does not know the key and is technologically unable to comply. But for such a low stakes system they would obviously never go through the trouble as it would cause more user friction than it's worth.
(You could have a privacy email be created as a totally unique auth key that's just stored offline on a User's apple computers and synced via an encrypted storage system).
Of course Apple could still associate source IPs for logins between multiple accounts.
