If you don't understand what the government/military technology is capable of, I'm sorry. I had a coworker who worked in and around extremely high level military surveillance years ago. Back then, they had the capability of turning on any cell phone microphone or camera and real time listen in. He wouldnt go beyond that, but did say/ the surveillance satellites in movies have nothing on current (even back then) capabilities. Imagine now
We are just now learning of Locate X who can pinpoint almost any phone location, tie it to advertising id's and view its movement history, and build an entire picture of what virtually any person on this planet is doing. That's just a company, not the government.
At this point in my life, I view anti tracking, ad block, encryption, alternate OSs etc. as keeping honest people honest. Military/govt. tech has ways around it all.
China, if you're listening...
