Man Flex,
I agree with you.

From the AF447 report: From 2h 10min 05sec, the autopilot then auto-thrust disengaged and the PF said, "I have the controls". The airplane began to roll to the right and the PF made a left nose up input. The stall warning sounded twice in a row. At 2h 10min 16sec, the PNF said, "So, we've lost the speeds" then "alternate law". The airplane's pitch attitude increased progressively beyond 10 degrees and the plane started to climb."

It certainly sounds "quite explicitly" to me. It is reported data, no conclusion necessary.

Relative to the mid-Atlantic A-340 zoom incident, I agree that was different in many respects. To begin with, erroneous speed was not the reason for the AP/AT disconnect, as was the AF447 AP/AT disconnect. For AF447, one of the first fault messages with cockpit effect was "PROBE-PITOT 1X2 /2X3 / 1X3 (9DA)", and IMO, this is what caused the AP/AT disconnect and lead to the cascade of subsequent events.
