Forcing the protocol to be open and documented and free for any user that can use the official site/client to connect to doesn’t have to mean forcing a standard

Forcing the protocol to be open and documented and free for any user that can use the official site/client to connect to doesn’t have to mean forcing a standard. You might want to require o rubies compatibility with old versions and deal with obfuscation or unnecessary changes as anti competitive behaviour, but otherwise just ensuring that anyone can create and sell or give away clients, interoperability and import/export tools, etc. would be an excellent step in the right direction. With no obvious downsides.
