I absolutely concur with that statement.
IF Airbus, and/or, the regulator, and/or THALES knew... that the pitots were not performing to specs... due diligence would require them to cause all the aircraft so equipped, to be declared un-airworthy. ....as that is the definition of airworthiness: "meets the standards".
