I am not sure that it is entirely correct to blame the FADEC for this accident. The POH clearly said that a dead battery must be charged before flight. The crew chose to ignore this warning used an APU to get it started ( unapproved procedure) and as a result suffered a double engine failure and crashed the aircraft.
I personally know of one Continental gas powered twin Cessna that suffered a double engine failure and crashed when the aux pumps were selected to "high" instead of "off" at 300 feet AGL after takeoff. The POH clearly warns that against this yet the pilot was ignorant of the limitation. How far do we have to dumb down an aircraft so it won't bite even if you do stupid things ?
