LOL "The head of a trading desk routinely directed traders to delete messages on personal devices and to use Signal, including during the CFTC's probe." 1000% this was done in-person, not in any electronic medium Probably by telling his right-hand-man or sub-heads who then distributed the message in-person, non-electronically as well
