I’ve always been under the impression that Signal is for secure, private chats and group chats amongst friends and small groups. While telegram is often used more like discord or irc, with “secure” and “private” group chats that are extremely large and semi-public. “Invite only” but invites are handed out easily. Those chats are pretty obviously not as secure, as basically anybody can join them and decrypt the chat. On the surface its somewhat more secure than discord, where discord will be scanning all chat content.
