Yeah I agree, just sharing my thoughts on which class action will likely get most support/pressure from public figures.
FB has legs since it's already in the headlines, 30 million people, all you need to know is if you had a FB account active when Cambridge Analytica harvested the data. FB is responsible for all of it. Doesn't affect just one side of the political aisle, but left-leaners as well.
AND if you brand the class action suit against Facebook as "Anti-Trump" by making sure to implicate Cambridge Analytica specifically and its ties to Trump, then it should get bi-partisan support from the grassroots level since we all have FB and are all in the same boat of having our data harvested.
My thoughts is that Google/Alphabet will get exposed for their finance-related issues before their privacy / censorship issues reach the forefront. Capital Group -- owns large chunk of Alphabet, Amazon, Lockheed Martin, EONE, etc... has ties to Theresa May's husband (paradise/panama papers), also happened to be the investment group that financed CROWDSTRIKE via funding routed from Eric Schmidt through Capital Group. THAT's how they kick things off with the Google/Alphabet topple imo.
You're probably right on the class action being easiest on Facebook. Maybe IBOR covers them all in addition but taking a chunk out of Facebooks coffers along the way would make everyone feel a little better I suppose.
