Overview

• WhatsApp is set to introduce third-party chat support to comply with the EU's Digital Markets Act, enhancing interoperability among messaging apps.
• The feature will be opt-in for users to prevent spam and scams, with a separate inbox for third-party chats.
• Interoperability will initially support text, images, voice messages, videos, and files, with calls and group chats to follow later.
• Other messaging platforms must use end-to-end encryption compatible with WhatsApp's standards or a less secure proxy for connectivity.
• Despite the potential for greater competition, concerns remain about privacy, security, and the impact on future feature development.
