9. All aircraft have instability characteristics

For some, like aerobatic and certain military aircraft, the instability is a feature, not a flaw. Transport category aircraft are designed to be more stable. It's entirely possible to design aircraft that are nearly impossible to stall or roll over, but that would present other problems which would be undesirable for the mission of these aircraft.

I don't know that they were so much as trying to fix a problem, or creating a solution in search of a problem. Aircraft stalling on climbout happens, but the reason is usually pilot inattention to where the aircraft is in the flight envelope and failure to take corrective actions.
