It’s pedantry, but significant pedantry: it’s not a private chat. You published the link; it’s public chat. Nazis, cops, the NSA, trolls… anyone can join, view, and publish everything anyone says in that channel. It may be anonymous, but it isn’t private.
The difference is important.
If you want a private group chat, you have to verify and curate who you let into the channel, and even then you can’t be certain. But encryption is less than useless for open-access chats, because it gives people a false sense of security.
