The aircraft was below 100ft so the A-FLOOR protection was not active and the engines in any case would probably still have taken too long to spool-up and provide the thrust to avoid the trees. The pilot was flying at 30ft instead of the briefed 100ft
If you look at the FDR data, you will see an AOA of 15°. The max AOA of the A320 is supposed to be 17°.
So why did the flight control law refuse to go up to this ?
The small margin between their actual alpha and alpha max could have allowed to fly over. Could have, I didn't run any simulation.
