Now, when the situation is confusing, the last thing you need is more details. The plane "knew" what was wrong (ADR disagree -> UAS) but did not inform the pilots in a quick, clear manner. It would have been the planes job to analyze those lower level detail problems and to build up a better message to the pilots "One pitot is malfunctioning. Apply UAS/ADR disagree procedure". Now it was left to the pilots to build up that info, from all the confusion and other ECAM messages. Also the messages are quite cryptic, with lot of acronyms and ohter things that puts pilots brains in even more pressure in a situation where the brains are already overloaded. I don't understand, from the engineering point, what is the reason, if not economical, to raise the level of the information in the planes for more easier diagnosis.
Just my humble opinion.

You want to know why the aircraft failed to pass along information that it's logic knew? I'll say this, then duck for incoming from certain persons who take years to design something that I the pilot have seconds to deal with.
The aircraft doesn't tell everything because there would be liability in doing so. Every part of this Godforsaken industry hides behind the pilot. No matter what, the pilot is legally responsible, which leads to manufacturers making statements to the effect that pilots are expected to follow procedure and understand situation before they act. If they produce a product that an attorney could represent in court as being infallible, they would then be responsible for the fallibility of that product. It's far easier to leave all final responsibility on the shoulders of those of us who veins carry a slightly more substantial mixture of guts and ice water.
Edit: and one more thing. Pilots are also guilty of the same mindset. This business eats its young in a non discriminatory manner.
