IMO that’s the wrong take about that crash. The stall warning stopped once the attitude was above a certain amount, which was an insane decision on airbus’s part.

You can see in the CVR that the stall indicator stopped many times despite them being in a stall the entire time. The pilot (like every other pilot) knew how to recover from a stall on paper. But he had the plane telling him his airspeed was good (frozen tube) and that bringing the pitch down was causing a stall.
