My bad, I misread.
Oh yes, they referenced attitude, just not explicitly pitch. CM1 mentions "Horizon" at 2:12:25 and both CM1 and Captain urge CM1 to "get the wings level" from 2:12:54. First GPWS alert is recorded at 2:14:16.

It seems we have to dumb down this discussion down to non-pilot level. By crosscheck. There are three independent pitots, feeding three independent displays, two of which can be switched to fourth source (ADC3). If they agree at the realistic value, and 183kt after one zoom climbs from cruise altitude is realistic, it works. If they don't, check that all three AIs agree and fly any of them. When I trained for PPL, pitch and power circuits were part of PPL syllabus and it was not fifty years ago, it was in 1996.
What overwhelmed the crew of AF447 is very similar to (and IMHO probably the same thing) that which wiped the crews of
KAL 8509 and
Birgenair 301 out of existence. First time they were faced with a bit more serious anomaly in flight was when they first really realized that the air is a dangerous place to be and they had no clue how to get out of their predicaments. As was predicted long time ago:

The fact that you've got Air Line Transport Pilot written on your license doesn't mean you fly any better. One day these pilots who fly for the money of the job, they're going to lose everything, the cockpit's going to burst or some such thing and they'll be left with a stick and rudder and they won't know how to fly.

Are you accusing BEA of deliberate falsification?

Of course they weren't but CVR mostly recorded the utterances consistent with being confused and clueless.

They are the instruments that work reliably for thousands of hours and all of a sudden they fail simultaneously, at the exact time airspeed goes unreliable, with bizarre fault that doesn't trigger DU monitoring. Yeah, right. For the record: I wasn't the one that first mentioned "Mad Hatter" in this thread.

Get the French report, go to page 96. If you are struggling with French: blue line is DFDR readout, red line is produced by simulator fed by winds and control inputs from DFDR. Blue and red are match. Magenta is simulator without any input on the stick.
Do you get it?

They are right; they didn't control the aeroplane anymore because CM2 has chased it away out of control and CM1 did not stop him! Both were pretty clueless from the start of the event.

Airborne equivalent of "Help, daddy, help!". It is tragic that when they realized that flying is no children's play they were left with only minutes to live. Not unprecedented, though.
