If I may second this notion.
From the A330/A340 incident ...
The pitchup trend continued for 17 seconds reaching a peak of 15° nose-up shortly before the first nose-down sidestick command was applied.
I don't get why it takes so long to make a pitch correction when such a pitch excursion is made. Can anyone familiar with AB FBW suites in that family of aircraft provide a bit of insight?
