The problems with the 737-MAX are inherent in the airframe design. It is unstable and it needs software to correct the instability. The 737-MAX is the only version of the 737 series with this issue. It is not the same "airframe" as all of the other 737 aircraft.

Can you be more specific about the nature of the instability? Is it lateral, longitudinal or directional stability that is at issue?

The issue at hand is longitudinal stability, specifically a positive but insufficient amount of it at high angles of attack.

People who run around parroting that the Max8 is "unstable" are telling you more about their level of knowledge of aerodynamics than facts about the Max8 airplane.
