If you read carefuly BEA's reports you will notice that most (if not ALL) affected crews wisely decided NOT to apply the 5° up/TOGA drill
They are still alive (if, arguably, undisciplined).
Re "undisciplined", yes, possibly, or alternatively they were highly-disciplined, knew how the drill should go and understood that any pitch-up at all only applied where the safety of the aircraft was affected (usually at takeoff), which is certainly not the case in cruise flight. Momentary loss of airspeed information isn't an emergency, it is a minor abnormal that, according to the drill, requires setting the MCDU to the GPS page to monitor altitude and levelling off for troubleshooting which means get out the QRH for the pitch-power settings, and wait.
The various reports of these events are sparse on details and we don't know why the crews actually kept level flight with the pitch and power in place at the time of the incident, (given room for minor variations due turbulence, etc), but we know none of them pitched the aircraft up.
