This is far more likely that Cox (the phone service provider) is listening in on phone calls than it is they're listening to conversations via inactive smartphones. Still, in most jurisdictions that's probably wiretapping unless it's well announced that the calls being recorded/analyzed. Makes me wonder if this is part of their business phone offerings where "this call may be monitored for quality" is common

They're just buying data from Facebook et al. They're full of shit.

Great, first the billionaire that is actually putting a microchip in people now this.

Man, it would be great if I found some "Fuck CMG" t-shirts. Too bad I haven't seen any ads for them...
