Re: Yet IPv6 networks were built to rely on and assume both BGP and DNS work perfectly.
If I were an author of espionage novels, this would give me a few plot ideas. Like that they might have identified some Apple internal service or system that carries unencrypted or easy-to-break traffic; because it is used exclusively within Apple's network, nobody bothered to fix it...
But I'll leave that to John le Carré and his colleagues.
