This. I'm trying to think of in that cockpit, and this happening under all that stress. The stall horn goes off. You make input changes. it starts again. You have 300 people on the plane, no faith in the instruments, no way to see anything outside, and are starting to panic. So you roll back the controls, and the horn goes off. But the controls don't make sense, so you try going to something more normal. The stall horn starts again. Oh... my... god. Turning off the stall horn when it's potentially unreliable.... that's horrible design. Instead have it make a different kind of sound, to alert the pilot to the fact that it has been turned off. I am surprised this has not been highlighted more significantly - this issue is all on Airbus, who designed and built the plane with this "killer feature" (literally).
