Take out all this discussion over laws and automation and what you're left with is a crew over the ocean in the middle of the night (low circadian time) who suddenly find all airspeed information gone, a plethora of warnings they've got to figure out and a few minutes to make the correct choice. This is not the first time it's happened, and it's not the first time it's killed people.
I'm not sure how you know that they found all airspeed information gone. There is no indication in the report that the airspeed information was false at any point. Only that for a minute the standby didn't agree with the PFD. I also don't see and indication of a "plethora of warnings".
If you ignore all the previous speculations and just read the new report there isn't much wrong with the jet except an AP-AT disconnect in turbulence.
