The report doesnt emphasize the big problem that confused the crew in:

-The stall horn discconecting below 60 kts.
-The big problem the automatic Trim can cause.

The FBW in the airbus doesnt have artificial feedback on the sticks so an automatic trim becommes absolutely necessary for hands off flying ( elevator neutral to cg ) if we want to make flying in this planes bearable for the pilot in a day to day operation.
Therefore,this trim being full up if commanded to do so does create a problem after the crew still has not figured out they didnt need to pitch up so much... specially because the trim up will stay there unless commanded to go down... making a dynamic neutral stability situation WITH a pitch up and high AOA taking the aircraft into a stall.

Thats why there are laws in airbus aircraft...because if there where none, almost all pilots would stall the aircraft with that lousy philosphy and hence, protections are needed, but guess what... that day there werent any protections available after pitots got frozen.
