Wikimedia and W3C log their chats with bots developed by themselves. I admit though that I am not expert in this topic, but I know that LiberaChat's policies forbid logging.
IRC archivers just idle on a server and record anything that comes by. You can do that with Discord. Matter of fact, I keep regular archive backups of a server we have that's full of news
Servers can be hosted by anyone; there is usually no account needed to join the chat; it would not randomly demand a phone number or an ID; it does not get pissed over people not using a very specific piece of bloated spyware... So nope, not against.
