Already 10 years ago, I got an email from a webshop I used to use once, informing me they were closing down. They'd happily sell the customer database to me, if I were interested. Mind you, they were so desperate that they made this offer to all their customers. Its anecdotal, and only tangentially related. But my point is, companies blatantly selling your data isn't exactly a new thing, and not really AI related either. They are doing this since a long time, but usually got less publicity.
