The sheared vertical stablizer is for now unremarkable.
In normal cruise and climb, even through turbulence, the use of rudder is limited. On this particular aircraft, yaw control is augmented by the FBW system and yaw damper.
While the ACARS readout does show a degradation from Normal Law to Alternate Law, and the warning regarding the Rudder Travel Limiter (most likely from the ADIRU failures), there is no reason the PF would from that point forward have begun stomping on the rudder pedals willy nilly.
To suggest otherwise is irresponsible at this point in the investigation. Speculation is fine for a learning exercise, but let's refrain from pointing fingers at the crew when not even 1/1 millionth of the data & facts are at hand.
