Quit
The world will never notice that you worked there, or that you quit. It's not important, and you won't think so later.
EDIT: However, thinking about this from the opposite position; perhaps the CEO is looking for advice regarding employees who won't take instruction?
Everyone does exactly what he says, so he should have no issues with anyone not taking instruction from him.
It just sucks to leave a meeting knowing that we are doing it the wrong way and can't do anything to fix it. I want to fix it.
