> Who's selling the data is the far more serious issue here.
Everyone who has it is selling that info, and nearly everyone who collects it is selling it. Until there are laws that actually protect us, we should stop giving companies our location data every chance we get and push for laws that prevent it from being unnecessarily collected in the first place.
"FBI is buying location data to track US citizens" ... "Until there are laws that actually protect us"
I don't see how we overcome that massive hurdle. It's not like those who ostensibly make the laws don't know and approve, and probably intentionally implemented that.
We now have full scale mass tracking and surveillance of the kind no one pre-9/11 would believe would have been allowed to exist in the form of the Flock cameras (of course it was an enemy Brit implementing surveillance in the USA) making anonymity quite literally as challenging as Winston Smith trying to move around without being detected to meet his love interest.
How are we going to get the de facto tyrants in the government to pass laws that materially disempower them by being unable to mass surveil everyone at any given time if they don't like what you are saying or thinking?
The problem with all the naysayers for all those decades is that once you have given up control over your own life and you have given away your rights protected by the Constitution, your enemies in the government are unlikely to simply give them back because you ask nicely. In fact, they will most likely aggressively move against anyone that even suggests that you nicely ask for your rights back.
