It stands to reason that user of the service who has agreed to the TOS that governs APNS and App Store sending unique device hardware serial numbers to Apple has also (legally) consented to IP address collection. IP addresses are less unique identifiers than globally unique device serials, so I assume Apple has already secured what passes for "consent" under the relevant privacy laws.
Again, nobody is questioning their access to that information. Where you typically go wrong is by asserting without evidence that they are performing additional activities without disclosing that. Surely you understand that having IPs be visible does not automatically mean retaining those records, much building a searchable database?
