It's sad that people are having this fearful response to technology. Yes, companies are tracking you, manipulating you subconsciously, and making money off you. But you don't have to take it as a threat. You still have agency over your life and you can decide how much you interact with tech and when. You don't have to run screaming.
In terms of being opted-in by somebody else: yeah, that sucks, and has been a danger ever since Facebook started auto tagging faces from pictures at parties. But we need to pressure them to add controls, not just pull ourselves away from society.
