Your statements below show you are not sure whose side you are on. You wrongly blame deactivated protection(because it wasn't) in one statement while in the other you are against the modern preventive innovations. FDs had nothing to do with alpha floor. FDs when both are off ATHR changes to speed mode and that would have taken care off their inadvertent entry in OP DES . B777 A/throttle is worse in SFO it quietly went to sleep as per design and suppose to wake up but didn't. FAA has asked them to improve it.
if Airbus had simply stated in training and manuals that having one F/D of and one on would inhibit Alpha Floor, {it was neither taught or in the manuals at this time} this crash would simply not have taken place.
the fundementals of aircraft handling are simply not being taught in many places, no amount of "magic" can solve this, certainly more "gongs and whistles" have not proved to be the answer.
Surely you can't remember everything but you could always take a breather before coming out with a howler like that.
