Their cavalier attitude towards ATC, ie. speed control; lack of informational communication with ATC .... and lack of prudent speed control, dependency (maybe) on automatic nose down trim during attempted recovery, which subconsciously perhaps the pilot at the controls was used to aircraft doing (I am unfamiliar with A320's, really all Airbi, and have no desire for that to change). Have no idea if they briefed expected flight control logic/action and what to expect prior to initiating the event.
