Imagine a world where suffering a data breach meant you could no longer collect, let alone hold or sell that class of data for a decade, and this rule preempted laws that required data gathering. AT&T would be nearly equivalent to an E2E service overnight. The lines wouldn’t be encrypted, so the NSA would still tap them, but at least there would be zero mutable storage in the AT&T data centers (except boot drives, SMS message queues, and a mapping between authorized sims and phone numbers). In this day and age, why do they even maintain call records? They don’t need them for billing purposes, which was the original purpose of keeping them.
