Summary : two unstallable airbusses stalled and fell into the sea.
There is thus something wrong with the flight control systems.
Bottom line.
Agreed. Sifting for minutiae misses the point. And there are already many things to learn by many parties. The report will try to pin the blame on some chain of causality ... but if we want safer skies then there are already many things to learn, by many parties. Tracking, air traffic control, search and rescue, manufacture, human-computer interface etc...
The business / marketing side of things seems also very important; from what I understand flight control systems were an important factor in Airbus's entry to market, to give it something new to edge into a mostly (at that time) Boeing market.
