Attorneys General from Colorado, Florida, Iowa, Nebraska, North Carolina, Ohio, Tennessee, and the District of Columbia, led by New York Attorney General Letitia James, have initiated an antitrust investigation into Facebook, seeking to determine whether the company "endangered consumer data, reduced the quality of consumers' choices, or increased the price of advertising."
The contours of the investigation hew closely to the framework laid out in Dina Srinivasan's seminal Berkeley Business Law Journal paper, The Antitrust Case Against Facebook, which does incredible, yeoman service into framing the obvious, manifest problems with Facebook in terms that even members of the bizarre Robert Bork antitrust inaction cult have to pay attention to.
