In this incident, as with Air France flight 447, pilot and co-pilot were holding the controls in opposite directions, and the software averages the input. In this case the warning that the controls were mismatched was not of sufficiently high priority to be issued (other warnings were taking precedence: You're about to crash). This user interface just continues to appall me.
With mechanically joined controls, it is impossible to have this happen. I think if I were designing a modern aircraft, I might retain physical linkage for just the reason.
