This is not idle talk. Think e.g. about personal credit. An important consideration in certain banking models is filtering out good from bad credits. Guess what, so-called "alternative credit data" which include social media activity is already a thing (search for it).
Its basically a digital wild west. Greed, hypocrisy, misrepresentation, collusion, corruption. As a rule, anything that is not be prohibited by draconian fines and license removals will be done. The honeypot is irresistible and people left on their own are just digitally illiterate idiots.
