"Meta Announces WhatsApp and Messenger Interoperability to Comply with EU's DMA Regulations"
Meta details its plans to implement interoperability in WhatsApp and Messenger with third-party messaging services to comply with the EU's Digital Markets Act (DMA) regulations, which require gatekeeper companies to open some of their services to competitors. The company expects third-party providers to use the Signal Protocol for end-to-end encryption and proposes a "plug-and-play" model for connecting to its infrastructure. However, challenges such as potential data exposure and loss of connection level signals are noted in the proposed technical architecture.
