Multiple state attorneys general have suggested they could pile on with their own investigations or lawsuits against the tech industry. In December, Karl Racine, attorney general for the District of Columbia, became the first when his office sued Facebook over the Cambridge Analytica debacle. And the FTC itself could open additional investigations, said Harold Feld, a senior vice president at the consumer group Public Knowledge. A recently established task force charged with reviewing past tech mergers could, for example, seek to determine whether Facebook's acquisition of WhatsApp or Instagram proved harmful to competition. "It's very clear that the settlement is not the end of the game," said Feld.
