That is exactly precisely what FB did allegedly. NYU was planning to research the amoung of disinformation (LIES) contained in the FB political ads and FB BLOCKED THEM.
Obvoiusly FB has something to hide and a great deal of money to lose. FB is all about making money. The bottom line.
So where are you on this issue? What does FB have to hide? Does its obscene wealth come from the extreme right and as such it doesn't want to upset all the little darlings who spend BIG BUCK much of which is DARK MONEY on it?
What do you think? FB is a public forum. ADS are run to gain an edge. The more lies the bigger the edge.
Liars stick with liars. Liars defend liars. Liars support Liars. Liars protect liars. And so it goes.
