Ed, wouldn't you want the aircraft to respond to your control inputs if you were flying it? If the pilot's stick inputs were to not be responded to or obeyed, don't you think there would be a greater cause for concern?
FBW or not, if I pull back on the stick, I sincerely hope the aircraft responds with an appropriate elevator command to do what I asked it to do.
Of course I want the aircraft to respond to control inputs but I wouldn't want it to change the trim. That is a very basic thing when flying in turbulence. In this case, it followed what was clearly an erroneous input by the PNF and trimmed them up into a stall, a no-no taught to every student pilot.
