There is no evidence at this point that the pilot made any rudder input at all. As you well know rudder dampening systems should prevent any overstress on the rudder even if the pilot did use full deflection, which is doubtful.
The bottom line is that we should all stop speculating about what caused this accident until all the FACTS are in. To do so is completely unprofessional, an insult to our fallen comrades, and worst of all it plays right in to the worst form of tabloid journalism. Accident investigation is a science. Good science takes time. lets wait and see.
