Meta is probably one of the more agreeable players in this racket, too. It hoards data; it does not share much of it. And it has a brand to protect. Data brokers are far worse because nobody knows who they are or what they collect, share, and merge.

This is a point that I have made in the past: while the big companies like Meta get a lot of attention (and rightly so) data brokers further down the advertising food chain do a lot, lot worse things. That’s not to say “do nothing about Meta”, but it’s an important point to note.
