Does the Airbus have a stab trim button on the sidestick? If it does, there is absolutely NO sane reason why, in almost 3 minutes, at least one of the pilots would not take control and push both the stick and the trim button forward to try to break the stall. There is also NO sane reason to explain why those pilots would expect the plane to NOT be stalled with the excess pitch attitude they had.
Regardless of any control laws or design flaws, there was PLENTY of time to get the airplane out of the stall, and they failed to even make a reasonable attempt to do that. THAT is sad!
