The fear of FOQA is the root cause of this syndrome, and the attitude negates the worth of the FOQA program. The key to resolution is more appropriate training and advice.
My advice: Be vigilant and sit on your hands: the system works well and rarely needs intervention.

I have seen the same thing, in cruise flight we had some fairly significant Mach excursions, approaching MMO the PF (in the left seat) slammed the throttles to idle
Of course the subsequent deceleration caused us to lose so much speed we had to descend
I was amazed at the level of alarm caused by some Mach fluctuations, not sure if he thought the aircraft would break up if we exceeded mmo or, as mentioned, a fear of foqua
