This whole Cambridge Analytica thing is such a nothing burger - I have yet to be given a concise reason how it was anything other than targeted advertising. Something that happens day-in, day-out a billion times over on all our "western" platforms in the form of ads. And no, the fact that this data wasn't "consented to" doesn't mean anything other than being a technicality. If anything, I'd chalk the whole thing up to anti-Trump hysteria that happened around that time.
