You're overcomplicating it. The existing members of the group have the plaintext of the older messages. So they can totally send those messages to new members of the group. If I can copy/paste the history of the group chat and send it to a new group member, then the application itself can do the equivalent behind the scenes.

- foldr 2y agoIn a public group that anyone can join without an invite it’s unclear why you’d even want E2E in the first place, so we’re presumably talking about invite-only groups. In that case, sending old messages to new members may or may not be a desired behavior, but it doesn’t defeat the purpose of E2E.
