Have the investigators (BEA) stated that the zoom climb was commanded by the pilot (stick) or is the jury still out considering that a computer function did it unrecognized by the pilot?
I focus on this early event as a possible critical causal factor needed to take a benign failure condition (temporary lack of reliable airspeed) to a severe condition.
To me this is a critical finding, because we can'y elliminate all failure conditions (ala loss of airspeed) etc. We are left with strengthening a minimization factor like pilot training. If there is another critical area that can be worked on in this causal chain that would greatly minimize a repeat of the event chain leading to a fatal accident.
