For example, I have been using Google or Apple for 7 years, and seeing that I was fingerprinted, tracked through third-party cookies, etc. I want to switch to a more private option.
But is it worth it? They know about me, they have now AI that can just use the behavior pattern for the last 7 years and still track me.
Again the question comes, should I become "privacy-focused" despite my data before I was "privacy-focused" used and sold?
Yes. the you that is most valuable to others, is you, as you are today, so right now is a perfectly fine time to embrace privacy focused practices!
