This attack on Cambridge Analytica is one of many prongs in the multi-pronged all out attack on Trump by the establishment.
CA was very successful in helping Trump win the election. Trumps campaign was able to beat the Democrats at what had been their own game - use of social media and detailed analytics. Romney and McCain were far outclassed by the Obama team.
But Trumps team prevailed and was superior. Therefore the Democrats must try to shut them down or hinder them as much as possible.
Spot on!!
The leftists are pulling out all of their stops, now.
As Andrew Breitbart and OTHERS have warned....this is #War
I agree with your premise (that Trump is undergoing coordinated mass-media attack) but for now I don't agree with your conclusion. I think Snowden used C.A. as an example to make his attack on Facebook appear to come from a completely different angle than the kind of censorship-based attack that the "right" is making on Facebook.
I say "for now" because while it appears Snowden's primary target is Zuckerberg, if other clowns in the media take the cue and raise a big stink over C.A. and Trump's use of their data, that will prove you 100% correct.
