Some still don't get it.
The MCAS system was working PERFECTLY and did its JOB very PROUDLY and exactly "as designed to do so". .
But it got "WRONG INFORMATION" from the AOA sensors/system, and it was only fed by a single probe => That can be seen as a AOA signal concept error..
Perhaps so, but if it was designed to keep fighting the pilot who was desperately trying to regain control of the airplane, then it was designed wrong. Certainly the MCAS did not malfunction, it behaved as designed, but when it apparently received the wrong AoA value from the single input and the pilot(s) desperately sought to recover the airplane, the MCAS behaved badly, unsafely and unacceptably.
It was designed wrong.
