This wasn't just pilot error, this is a systemic problem affecting the airlines and the industry as a whole. PPLs start their ATPL training knowing how to recognise and recover from a stall - that this knowledge is not periodically revised and enforced is a sad indictment of the real issues that cost-cutting and poor corporate morale produce.
I understand your desire to shill on the part of the airline manufacturer as it seems your livelihood is attached to it. Nevertheless, this accident is primarily a manufacturer's problem, not an operator's problem. That's the historical trend. For more than 75 years the liability of the manufacturer has been increasing, not decreasing. You can blame that history on the pilot's union, you can blame it on the press, you can blame it on whatever you like but casting blame doesn't change the underlying reality it just evidences your irritation at it.
The underlying reality that Airbus (and Boeing for that matter) can't escape is this. In a matter of 30 seconds the PF managed to kill 200+ people and cost the people of France hundreds of millions of dollars. That French crew did more damage to France in blood and treasure than the recent riots in England did to the English.
How could so few people do so much damage so fast. Paeans to pilot competence ring hallow. As a cultural matter in the Western world we expect technology to solve our problems. Right or wrong, good or bad, that is the expectation. And the person responsible for the technology and the hardware in the airline business is the manufacturer.
