I'm not an Airbus man. But as far as understood from that incident, the cause was an "software feature" in the airbus that limits the trow of the ailerons after touchdown.
Unfortunately they had a gust and touched down with the downwind main gear, where after it was impossible to bring the wing down with the limited trow.
I believe Airbus reprogrammed the software after that incident. Correct me if I am wrong.
You're wrong!
The cause was part overcontrol by the HP and then a dual inputs (both ways) to correct which caused excessive roll one way then the other causing the contact of the wingtips. Airbus did change the roll authority of ELACs around that time but it was to
dampen roll in Flap 3.
