 NIP-whatever MLS stuff also solves for the Telegram broadcast group use case as well 😉 
 How? By making the encryption keys public? 
 No there is a mechanism (via an extension) to join a group without an invite. With really basic admin permissions (which I’m adding as part of NIP-104) you can limit who can post or not. 

That said, it’s probably overkill to use mls here.
