That's because the 'pitot first' theory is best supported by the flurry of ACARS messages over a 4 minute period.
The total loss of ADR data is survivable, if handled correctly by the crew, so there may have been more hardship faced by the pilots before they lost control of the aeroplane. Severe turbulence and structural failure comes to mind.
Some strange ACARS messages have not been fully explained yet, like the line about the 'IR2' and the failure of PRIM1 and SEC1.
