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.
