WhatsApp works on interoperability with other platforms so that its users with iOS devices can communicate with others on third-party platforms without having to have a Meta account, a feature that responds to the obligations imposed by the Digital Markets Law. The Digital Markets Act (DMA) establishes new rules for large technology giants, considered as ‘gatekeepers’ or market controllers, by which they must assume a series of obligations and prohibitions that guarantee fair competition. in the digital sector. Based on this scenario, Meta has developed a communication alternative within its own platform, so that it will allow WhatsApp users to communicate with others on platforms such as Telegram or Signal without the need for them to have a Meta account. This was discovered last September by WABetaInfo in the beta of WhatsApp for Android 220.127.116.11, in which it noticed a new tab called ‘Third-party chats’. This portal has now displayed the same option in the latest beta launched through the TestFlight beta program for iOS and, more specifically, in WhatsApp version 18.104.22.168 for the operating system developed by Apple. WABetaInfo has clarified that this chat interoperability feature is being developed while preserving the Meta principles in relation to the end-to-end encryption offered by the messaging platform.
