About Matrix Matrix is an open protocol for decentralised, secure communications.
Matrix Manifesto We believe:
People should have full control over their own communication. People should not be locked into centralised communication silos, but instead be free to pick who they choose to host their communication without limiting who they can reach. The ability to converse securely and privately is a basic human right. Communication should be available to everyone as a free and open, unencumbered, standard and global network.
it’s complex to make dozens of technologies work together under an umbrella (Matrix). Particularly when those technologies have a vetted interest in not being interoperable.
There are companies that provide an offering with Matrix, e.g https://www.beeper.com
