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?
Of course. Very few people here would have been privacy conscious when they first started using the internet. There will inevitably be some amount of data available about all of us. The key thing to realise about privacy is that it is generally more about damage limitation/mitigation rather than outright prevention.
