You are right. We will all be in some databases, whether we realize it or not.
Our financial transactions also are in some databases.
Perhaps off topic, but I went to the ATM to get some cash. I prefer to still use cash for some things. In the line of people at the ATM, every single one,,including me, appeared to be middle aged or older. I suspect younger people simply don’t use cash much anymore, and probably don’t even think about how they are in a database, and are being tracked.
If/when, you/I/we use an ATM, we have a lot of pics taken and looped into our card’s number and what we did at the ATM.
