Gatekeeper Creep in App Platforms

Regulators are extending 'gatekeeper' designations beyond core OS/app‑store functions into adjacent services (ads, maps) that meet activity and scale thresholds. Treating ad networks and mapping as DMA gatekeeper services would force new interoperability, data‑sharing, and fairness obligations that reshape ad markets, location data governance, and default‑setting power. — If enforcement expands to ads and maps, regulators will be able to regulate the commercial plumbing (targeting, location data, ranking) of major platforms, with knock‑on effects for privacy, competition, and where platform supervision sits internationally.
