Most peoples lives are as simple as going to school and work, raising a family, taking vacations, paying bills, and then passing away.
There will never be a moment where they can say “Yes! My avoidance of Facebook and Alexa for all my life has finally paid off! Hahaha!”
The only people who can say that are people who have good reasons to hide: drug dealers with multiple lines of business, professional black hat hackers, home grown terrorists, life insurance fraudsters, etc.
The average person has nothing of interest to offer except more information about them in order to better perceive trends and distribute ads to them so that maybe they buy something.
