> AFAICS non-circumventable ephemeral messages is incompatible with user-controlled system. Unless the ephemeral part refers to the user's own side of the conversation, i.e., delete messages from my history some time after I read them. Together with a secure storage that prevents messages from being easily recovered from memory dumps, this protects the user in scenarios of devices being captured by the adversary, exactly like this one. AFAIK is what Signal advertises for it's timed messages; Telegram, OTOH, advertises its self-destructing messages as something magical that works even for the other side.
