They could get that region-level information already from ISP routing info. This ratcheting up of info means: The household owner's name, their affluence, postal code, phone number, a cross match with google street view and all info that shows (new car?). The last thing I want is to watch a home reno show on a tablet and then be deluged with phone calls soliciting for new windows. This is definitly not 'right'. (edit: on top of watching ads that glitch and repeat.)
