Since here's yet another thread about Facebook, I'll ask somewhat unrelated question I already asked on HN, but never seen an answer: can somebody explain, why the scandal around Cambridge Analyica (and, "suddenly", a bunch of other rumors about FB) escalated just now, even though we knew about FB, Cambridge Analytica & Trump for about a year at least (well — I knew for a year, sure lots of people knew earlier)?

I suspect I know the answer, but I have faint hope that it's not true and somebody can provide a bit more "sane" explanation.
