Is there anything stopping Musk or any other employees for that matter from just looking at drafts, DMs, etc… At the time of the takeover, were there processes in place to make sure any one employee could not just access DMs with ease? Hopefully there were, but no doubt Musk could bypass them easily now that Twitter is ‘his’. If there’s to be any trust in DMs, they need end to end encryption, short of that, an independent board to grant access, like his planned content moderation board. I’m not holding my breath…
