Frankly, Facebook and their proxies always speak in meaningless nonsense about everything. If you asked Zuck if he ate kittens, you’d get some reply about facebooks mission and why cats are important.

For some mysterious reason, all explanations for the “Facebook is listening” phenomenon are uniquely cogent, clear and dismissive.

Personally, I have zero doubt that a downstream “partner”, data provider, or affiliate is processing audio data of questionable origin for ad insights. Call center companies with tight margins do it, why wouldn’t an ad company?
