What "ergo" issues? The yoke would not have fixed things - connecting the sidesticks would not have fixed things - this is a case of a temporary loss of airspeed data leading to panic, confusion and a crash. Nothing more, nothing less. There is nothing to suggest that the PNF would have been more inclined to take over had his stick been moving, and a lot to suggest that the barrier was psychological in nature, being uncertain as to the limits of his authority. He didn't intervene because he was afraid of a writeup if the Captain decides that the PF is correct and that he overstepped his bounds as PNF.
CONF, Lyman, jcj and others are trying to hammer the facts to fit the decision that they have already made, that Airbus must be found entirely at fault no matter what and that the hideous old yokes are safer (tell that to Captain Loft of EAL401).
