>but plenty will just sell everything to data brokers.
Again, "sell" implies that there's some company where they'll accept data from anyone and pay them for it, which so far as I can tell doesn't exist. That's not to say there's no selling going on. The fact that data brokers exist means they do, but that doesn't mean every business is in a position to "sell" data.
It's worth nothing. This is an online myth that marks out the user the way the sentence "Expert in JAVA, AWS, GCP, Oracle, and GIT" on a resume marks out the candidate.
