if its not not end-to-end encrypted, what does that mean? whats the method that govts access these messages?

You can simply join those channels. Getting an invite is not hard, or even unnecessary, from what I hear.

End-to-end encrypted means that the server doesn’t have access to the keys. When server does have access, they could read messages to filter them or give law enforcement access.
