Yes, they're a pack of liars
"we have decided to eliminate all location aggregation services – even those with clear consumer benefits"
This makes me wonder which of those services they consider having "clear consumer benefits". It's location-based advertising, isn't it?
"Verizon claimed that location data was only sold if subscribers had explicitly agreed to it"
And by "explicitly agreed to it", do they mean that it was buried in the lengthy legalese called "terms of service" that users clicked an "I agree" button for?
"AT&T has no reason to believe that there are other instances of unauthorized access to AT&T customer location data,"
Yeah, but what about access that they authorized?
"there has been no response from Pai"
No response is needed. We already know what he'll do about it: his best to protect the carrier's ability to keep on as they always have been.
