"Did they cut ties the same way they cut ties with "Cambridge Analytica" ?" This is completely nonsensical. Cambridge Analytica was a company that used personality quizzes on Facebook and took advantage of the open-to-everyone social graph API when it existed.

And their data was all bunk, too, as a professional digital advertiser I can promise you they didn't move the election one way or the other.
