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?
You should care, but it’s maybe more of a question about how much and about what specific things. There are some easy-to-do things, and then there’s others that get exhausting
Some of this depends on why you care about privacy and where you live. It’s a lot of work, and in some places, like the US, there’s a lot of data being sold anyway (credit/debit cards, tvs, streaming services, and stores can almost all sell some of your data and it can be difficult to stop them). Keeping Bluetooth on also enables you to be tracked going in and out of stores and other various locations.
It can be a lot of work, but some things are more worthwhile than others. There are likely some things you’re just going to have to live with.
