Last week, the European Union (EU) announced the first set of gatekeeper tech companies and gatekeeper services, and we’ve already discussed what it means. For example, iMessage isn’t a gatekeeper yet, so it doesn’t have to support Google’s RCS.
But Apple’s iOS and App Store are gatekeepers, so sideloading support must be coming in a future update to iOS 17. Similarly, Meta’s WhatsApp and Facebook Messenger are gatekeeper chat apps that will have to support third-party instant messaging apps.
