"The FTC has failed to plead enough facts to plausibly establish … that Facebook has monopoly power in the market for Personal Social Networking (PSN) Services," U.S. District Judge James Boasberg wrote in his opinion, released before a trial in the cases had begun. "PSN services are free to use, and the exact metes and bounds of what even constitutes a PSN service—i.e., which features of a company's mobile app or website are included in that definition and which are excluded—are hardly crystal clear. In this unusual context, the FTC's inability to offer any indication of the metric(s) or method(s) it used to calculate Facebook's market share renders its vague '60%-plus' assertion too speculative and conclusory to go forward."
