She starts this off with a lie, as they have the metadata, which is more valuable than the actual communications. As most tie a phone number to their account, they know who is using it, and if not by phone number probably IP address. And this woman has got to be a spook. And the laugh tell after she says she has the luxury of being honest speaks volumes. Was her slip of “we have so much signal” while talking about surveillance also a slip? She made an effort to re-address it as data. Another hilarious observation as she has a history in AI research, when she occasionally uses AI for research she checks sources as they’re inherently inaccurate.
