Just to clarify my point I’m not condoning this at all, but the telcos themselves have been selling live location data of their subscribers to aggregator services for years.

It’s really infuriating to me that people say Google or Facebook are “selling their data” (they’re not, they hoard data and sell targeted ads) when Verizon, T-Mobile, and AT&T literally sell your live, personally identifiable, non-aggregated, location data to third parties, hiding behind their subscriber agreement legalese.
