Here is the key quote:

But the author of the study, Ronald A. Hess of the University of
California, said that the design of the rudder was conducive to such
oscillations. One problem, he found, was that on the A-300, the amount
of force needed to start moving the rudder was relatively high, and
the total range of motion allowed at that speed was only a little over
an inch, making it very difficult to apply any amount of rudder less
than its full extension. In addition, rudder application does not move
the plane instantly, and the delay might encourage a pilot to keep
applying the rudder until the aircraft moved further than the pilot
intended, according to Mr. Hess's analysis. The natural reaction would
then be to apply the rudder in the opposite direction. (end quote)

More likely Hess is full of **** and should look further into the
circumstances of the crash.
