Google and Facebook allegedly colluded to bypass Apple's privacy protections, with Google's 'Jedi Blue' project aiming to identify users on Apple products and set quotas for Facebook's ad wins. The claims are part of an amended complaint in a Texas antitrust case against Google. The complaint also alleges that Google secretly made its own ad exchange win, even when another exchange submitted a higher bid. This behavior is seen as a threat to fair competition in the online ad market.
