AF447 is more complicated than just that sidestick issue, if you look at the accident report closely.

The contributing factors were loss of outside air temperature and airspeed sensors because of icing, a dark moonless night above the ocean, and flying/falling outside of the operating range of the stall horn (when they pitched the nose down, they started recovering from the stall, airspeed went up, and the stall horn activated. when they pitched up, they went back outside of the operating range, and the horn muted).

A big contributing factor as well was that in an airbus, in normal operating conditions, pulling the stick all the way back will configure the aircraft for the best rate of climb (which can be different from just putting the elevator in full climb conditions). Due to the pitot tubes being iced up, the flight computers were in Direct mode (where movement of the sidestick is directly translated in movement of the flight controls, without computer intervention), which didn't help.

Almost that, they were in Alternate Law
