In hindsight, with all these informations available to us, they would certainly have acted differently. But it looks like a tunnel vision issue up to this point, like if something took all the PF attention: it is not even sure that a giant red warning "THS +13 degree" painted on his PFD would have made the outcome different if he was believing to do exactly the right thing.
This THS information would have been paramount only if he had tried to pitch full nose down but lacked from elevators authority. Now, was this even attempted before it was too late?
If not, the main issue about what crucial information didn't reach the PF in time lie certainly elsewhere.
Well it certainly looks like they made nose down inputs, in a tentative fashion, and got stall warnings back for their efforts:

From the BEA statement

At 2 h 12 min 02, the PF said "I don’t have any more indications", and the PNF said "we have
no valid indications".

At that moment, the thrust levers were in the IDLE detent and the

engines’ N1’s were at 55%. Around fifteen seconds later, the PF made pitch-down inputs. In

the following moments, the angle of attack decreased, the speeds became valid again and the

]stall warning sounded again.
