EU Opens Antitrust Investigation into Meta’s WhatsApp AI Gatekeeping (4 Dec 2025)

Europe’s complaint echoes the EU–Microsoft media-player case of 2004 (497 m € fine) and the 2017–19 Google Shopping saga, where bundling a dominant platform with a proprietary service was ruled abusive. The long arc here is regulators wrestling with ‘gatekeeper’ power as communication layers (telecom in the 1920s, browsers in the 1990s, app stores in the 2010s) become essential distribution rails for the next technology wave—in this instance, conversational AI. By moving before the market fully locks in, Brussels signals a shift from ex-post fines to ex-ante deterrence, aligned with its broader Digital Markets Act philosophy even though the legal basis is classic antitrust. Whether the case succeeds or not, it tests how much sovereignty governments retain over privately owned digital infrastructure; the outcome could shape who can reach billions of users through chat interfaces long after today’s platforms fade—much as the 1956 Bell consent decree opened U.S. telecom equipment markets for decades.
