The long-awaited antitrust trial between Meta and the Federal Trade Commission kicked off on April 14th. Over about two months, DC District Court Chief Judge James Boasberg is hearing arguments about whether then-Facebook illegally monopolized the market for “personal social networking services” through its acquisitions of Instagram and WhatsApp.

The Meta chief executive testified in a landmark antitrust trial that it was business as usual when he bought rival apps. He denied he was trying to snuff out competitors.

Mark Zuckerberg testified in court that he acquired Instagram and WhatsApp for their value, not to eliminate competition, countering FTC claims of monopolistic practices.
