It wasn't the dive that did the damage; it was the pitch rate which put people into the ceilings and back onto seats/carts/armrests, which in turn caused the injuries. Such was the nose-down attitude that the pilots could not see the horizon until pitch control was restored. Fortunately, the pilots in the flight deck had their seat belts "securely fastened".

what other words would you have the ATSB use if indeed they have assessed that crew actions were "timely/appropriate/prompt"? I don't see your selective quotes as praising the crew but, rather, stating the facts as the ATSB found them. The "complete non-recognition of the fact that the flight computers are capable of making control surface deflections that will result in vertical accelerations of this magnitude" is surprising though, and I'll read the report to form a view on that.
