I am a big fan of John Mc Afee as he has the best, most pragmatic insight into tech spying. He basically says that devices are designed to spy on you for the purposes of convenience. They know your location so you can find a restaurant nearby, for example. The whole operating system of smart phones is ego-centric and focuses on meeting your needs. So it has to look at you. He also goes on to say that hackers simply exploit the operating system and what it was designed to do. Phones are designed to serve you and so have to spy on you to better do that. Check out Johns interviews on YT. He has a brilliant take on the whole issue of privacy.
