I think collection might be what we should ban.

Even the more conservative tech companies have no qualms about "anonymizing" data then sharing it.

(also "sale" is a very weak word. many companies "never sell" data, but they collect it, they share it, etc)

Doesn't even have to be a sale. The boundaries of US bases in the ME during our conflicts there could be very reliably be mapped inside Strava, et. al. because the soldiers would be posting workouts.

Same with aircraft carrier movements.
