They were incredibly quick to blame the pilot. Which is often the precedent for unexplained crashes - claim pilot error as early as possible. Easier than saying "we don't know what happened" which is PR suicide. Also infinitely preferable to disclosing technical problems which could ground your fleet, and raise questions about similar aircraft. Operational failures put the whole system under the spotlight, which is politically damaging.
Blaming the pilot is a tried a tested corporate and operational strategy. It may well turn out to be the pilot's fault, but I've found it slightly disturbing how quickly the focus has shifted to the pilot based on seemingly spurious evidence and conjecture. He sounded like he was breathing normally so it was suicide? He may have been depressed? A dead 27 year old doesn't stand much of a chance against billions of dollars of commercial interests.
