At last! Now they need to admit full responsibility in their management pressing engineers to move the center of thrust, fundamentally changing the flight envel

  That's more of an issue with two competing goals: higher efficiency (which larger engines help with), and keeping the same type certificate, which only requires difference training for the pilots, instead of a full training regimen. Because the original 737 was low to the ground, the under wing engines have been a design issue since turbofan engines became common. Each time the plane has been updated with newer engines, they have been larger, because higher-bypass engines, which have larger fans, are more efficient. The only way to fit larger engines on the Max, while still having acceptable ground clearance, was to shift the engines forward. This changed the center of thrust.
