I disagree. The modern act of viewing a digital ad produces more data than people realize. How long you looked at an ad, whether you clicked it, whether you skipped it or tried to hide it, etc. All of those implicit actions create data that is then surrendered to the collector.

Yep, no argument about user metadata. My point was specifically about location data, which users do not have to give.
