in actual fact, none of the chat protocols have solved any problems. the biggest reason to update to marmot MLS is it's a unified DM/group chat. at all times, forever, and from the beginning, AUTH has always been the thing that provides metadata security. you only have to read the architecture of matrix, signal, and the rest, to understand this. but even today, we here this "we don't go to ravenholm" meme about nostr DMs and you are not thinking bro. not thinking Auth is what makes privacy metadata security possible. you can get an answer to that question in 5 seconds with any LLM. do yourself a favor and stop making yourself sound like a stupid person to anyone who understands distributed systems and security
