Both sets of pedals are of course linked so that the second pilot could never have brought the helicopter out of this predicament. Would an input monitoring and control system like on large airplanes have avoided the crash?

There’s an answer [0] on Quora that describes helicopter instructors having to deal with students frozen out of fear and wrestling for control of the inputs. Nightmare.

Not at all, for example Airbus aircraft "helpfully" average out the inputs. There's a dual input warning, but warnings are weak at preventing accidents.

Some instances where the awful UX around the handling of dual input by aircraft contributed to incidents:

IMO, this is a critical design flaw with all current aircraft that should be addressed ASAP but what do I know :)

True, though at least they are not physically linked and you can disable the averaging.
