Facebook and Google should be broken up and stripped of their liability shield if they continue to sell advertising, argues progressive think tank the American Economic Liberties Project in a policy brief out Wednesday.

The big picture: The report ties together three major threads of the techlash: the idea that tech giants are too big; the concern that they harvest too much private data; and the threat to rein them in by taking away their broad legal immunity.

Details: The brief blames Facebook’s and Google’s ad-driven business model for the recent spread of conspiracy theories and violent rhetoric on their platforms following the police killing of George Floyd.
