I wonder why most of the blame is attributed to the pilots, when the report states: "...a rinse with fresh water was performed on Monday 24 November 2008, without following the rinsing task procedure in the aeroplane cleaning procedure, and notably without any protection for the angle of attack sensors."
As far as I understand this is the main cause, pilot errors came only after that, caused (again as far as I understand) by lack of failure information presented to them ("The system surveillance did not warn the crew of this blockage...") and system design which made it difficult to recover from the first stall ("The changes of law that followed did not allow the auto-trim system to move from the nose-up position").
I don't say the crew is entirely not to blame, but they it seems as the automation failed first and foremost.
