This answer ignores some known details of the story. Cambridge Analytica didn't just buy targeted ads from Facebook. They used a sockpuppet to release a fake "take a personality profile" app, which then allowed them to gather tons of data against the Facebook terms of use. The CEO of Cambridge Analytica has also been recorded telling a (fake) potential client that they routinely blackmail people using prostitutes and who knows what else.
