There was never a chance that Trump would listen to any "council".  He formed them to basically stick it to corporate America that saw him as a reality TV joke, to let them know that he was POTUS.    Trump was and is, basically Archie Bunker come to life, and horrifyingly leading the country.  For those CEO's that stayed on or tried to stay on, there's no whitewashing it, they wanted something from Trump and knew the best method was to stick close to him.  They hoped to "steer policy", and "advise"...they all deserve each other.
