Yes, that's what I said. The artificial behavior would be fine if the pilots actually knew it was artificial and how it was being done. That lack of understanding and training is the critical error, made worse by a poorly designed system that failed too easily.

If I remember correctly, the behavior you promote as "fine" is forbidden by the regulators, and not accidentally.

If it’s prohibited then how was it certified?

Without the active MCAS the plane would have not been certified because the behavior of controls is then not inside of the prescribed limits.

I was talking about the the artificial behavior, so if it was certified then it was deemed allowable to have a stability control system maintain the necessary behavior.

If the plane must have natural behavior, then MCAS would not allow it to be certified because it's artificial control.

Then I misunderstood your point, sorry.
