That's a very good comparison. (The Wikipedia article on this isn't very good, though.) The Airbus flight control system (not the autopilot) in "Normal law" mode will prevent stalls, and it's normal procedure to pull the stick all the way back if you want the nose up. The control system will keep the control surfaces just below the stall point.
Flight 447 had clogged air speed sensors. The flight control system detected this and dropped to "Alternate law", which does not have stall protection. In "alternate law" mode, pulling the stick all the way back will, as in most aircraft, cause a stall. This drastic change in flight control confused the pilots. This despite them having been trained for a drop to alternate law.
Airbus has redundant air data sensors, but not, apparently, with enough redundancy.
