I think "defector" is the wrong terminology here, since it's likely that most - if not all - the US based execs who weren't charged handed over these chats to the SEC.

It is noteworthy how often this happens. Many of the people found guilty of sedition after the DC riot had the same thing happen when the majority (or a large minority) of people in their encrypted chat groups handed over them over to the FBI.

Is there an E2E encrypted chat app that does disappearing messages and doesn't cache them on the client?
