The flight control software wasn't worked on by the infamous $9 an hour engineers. That was the multi-function display, on which one could only actually get as far as possibly contributing to not displaying the AoA disagree warning if I recall correctly.
What it does demonstrate, however, is Management's ruthless devotion to chasing the bottom dollar. What further probing may have been done by someone more deeply invested and dedicated to the task? I don't at all blame someone only getting $9 dollars an hour for "Yes-manning" it. I do, however, blame the exec woefully ignorant of the environment and effect on overall culture that has. When you start engineering for the sake of financials like that, you intentionally invite writing checks your work culture can't cash down the road.
My two cents.
