Opsec is sacred in militaries and for good reason. Nobody should ever know anything more than the absolute minimum required to do their job, anything else is information that they could give up or have tortured out of him. Poe was just a nobody fighter pilot, there was absolutely no reason Holdo should've told him anything, especially when she knew there were traitors among their ranks. IMO, Poe is completely responsible for the attempted mutiny, and really should have faced greater consequences
Was Admiral Holdon really mistaken when she wouldn't tell anyone her plan?
[CANON]He wasn’t the captain, or even acting captain. His demotion, as stated in the film, made him no longer an officer anyway.
There are so many presumptions being made about why he should have been told more, but there’s absolutely nothing to back it up.
No. That's a fundamental misunderstanding of what demotion means. Demotion just means reduced in rank i.e. Wing Commander to Captain or Sargent to Corporal. It does not mean stripped of Command - technical term is Relieved of Command. A CAG who is reduced in rank from Wing Commander to rank of Captain but is NOT stripped of his CAG Billet is still a CAG, he's still a senior officer as far as the chain of command is concerned. The only real impacts of the demotion would be reduction in pay, prestige/humiliation and stunted career advancement. His immidiade term responsibilities wouldn't change.
Him being acting Captain stems from him just being the last senior surviving officer of that ships crew. It's an automatic assumption of authority when you're next in line in order to maintain a smooth and orderly transfer of command. I don't actually think Poe was a good officer or would have been a good Captain or even Fleet Commander It's more that Holdo was creating such an incredibly toxic command atmosphere a total breakdown of discipline was inevitable
So, you know the entire chain of command for the Resistance?
His duties and role did change, Leia made that clear.
Well, we do know the entire Command staff of the ship was on the bridge when it got vented and that Poe was not. And sincr authority flows in straight lines based on a rigid hierarchy based on ranks the next senior guy is in charge and the movie makes it pretty clear or at least implies heavily that Poe is the next senior guy left alive from the ships crew.
No, she makes it clear he's demoted and in shit. She never says he's no longer in a position of Authority. Leia being the hands on leader she was and in a small enough command structure decided she was going to exercise increased personal oversight on Poes actions. That again as I've tried to explain repeatedly to you is fundamentally different from being stripped entirely of Command and removed from a position of authority. He was in serious shit, sure but he hadn't been stripped of his role yet, not entirely. He probably would have been at the first calm moment- and he might have even deserved it but Leia wasn't an idiot. That exact second was not a good time to completely shake up the Command Structure and be seen to be punishing a highly respected member of the Resistance. A member who did just lead an assault that killed a super capital ship in front of everyone no less
