What's really funny is that this has been known all along. Analytica even boasted about it on their website. That page was removed after a few weeks.
FB security staff went from 120 persons to 3 in 2 days. From what I hear, they informed management several times this was happening. And now, it seems management was planning on blaming their security dept. That is, after lying to investigators and even congress about it.
Another funny thing is, the Russians played along with this game, but for far less money. They just bought some ads on FB, after figuring out that click bait ads got rated much higher by FB than average ads.
And now it seems the Russians also bought a French president?
How many others to they own already?
