One way to answer that is to ground the question in comparable physical situations. The owner of a bookshop you frequent often would not be disloyal making a recommendation based on knowledge of your preferences acquired through previous interactions. That's fine targeted ads.

But if they let a third-party camera capture a facial print plus the books you buy, and that was then used to make the same book recommendation when you visit a random airport bookshop, that's disloyal.
