So the whole point of MCAS is to basically create an emulated flight envelope more similar to how previous generations 737s flew just to avoid a type rating re-certification?
People died because Boeing was playing with emulators in real life?
The shared type rating was a huge draw for airlines. Without it, the 737 MAX 8 would not have been nearly as popular in orders as it was.
Boeing got very greedy and multiple failures have occurred along the way. MCAS on passenger planes is not unheard of, and has been implemented for various reasons before including shared type ratings. It was just never botched across the board this badly before.
The biggest failure as parent comment correctly notes, is MCAS was given significantly more control authority than originally planned after flight testing showed it was ineffective as per the original design. But this change in control authority didn't trigger a review process which would have reclassified it from non-critical to critical system.
