Further that Low speed stability protection change from AOA to Airspeed based and the symbols on the speed tape change from Alpha prot /Alpha max to Vsw.
With the flaps/slats in use and 5 to 10 kts above stall speed the Aircraft will induce a forward demand on the elevators, which the Pilot can override.
This was not applicable to AF 447 in cruise.
So any pitch up/down demand was as a result of the Pilots alone, they did not have any protections helping them.
Also don't blame the THS trimming up to 13 deg nose up. It was a result of the Pilots demanding back stick pitch up ( to counter what they thought was an overspeed ) the speed obviously decayed during the manoeuvre requiring more and more trim to help it satisfy the Pilots demand.
