I think part of what draws people to any messaging platform is continuity with the other services on the platform. The actual messaging experience can be duplicated or exceeded by anyone, like how RCS has made the humble text message more powerful and compatible than anyone at Apple could comprehend.
With this idea, would any messaging platform that became ultra successful be then required to allow other platforms to message their users? Which platforms are allowed? How is spam managed? What about special privacy features like what's built in to Signal or Telegram? How do the platforms manage linking to content embedded in other parts of the platform (think Instagram posts/reels/messenger).
