You’re still missing the fact that public chats can’t be adequately protected.
Depends what you mean by “adequately” 🤔 With perfect forward secrecy (which matrix and signal have), seeing past messages isn’t possible. Seizing the servers is also not very useful unless people are connecting directly to the server. Anonymous public chats running on overlay networks like I2P and TOR might not even need encryption (although I wouldn’t trust a server that didn’t).
Where something publicly exists anyone can set up a local archive to capture anything, regardless of what’s available at the moment of joining the chat. Also telegram has such a setting too. It’s useless when someone really wants to get you. They won’t need an access to telegram servers to get you.
