Airbus does it too. They have several control laws that are used to provide flight envelope protection. It was the pilot's failure to understand his plane's software that caused AF447 to crash. Essentially he didn't realize that the flight control software had changed modes, that it wasn't providing the normal handling augmentations, and that his inputs were putting the aircraft into a stall, which caused the crash.

Build unstable airframes? Not outside of forward canard jet fighters.

And that pilot crashed a perfectly fine airliner after he lost situational awareness and then did the one thing you should never do - pull the steering column back in a mad panic until the plane stalls.
