UK Judges and Coroners are no fools. You only have to sit in a courtroom and watch to realise this.
They are extremely learned and intelligent. They collect evidence and come to neutral unbiased pronouncements.
I think the real question about the recent A330 and A310 crashes is not necessarily that the Airbus is flawed any more than a Boeing is, but why any pilot would think that holding full backstick/yoke at 37,000' or aggressively pumping the rudder pedals in turbulence was an 'acceptable' thing to do to an airliner??? Both these actions would have crashed a Boeing just as it did the Airbuses.
The real investigation needed here is how do some pilots somehow get through the system with these fatal flaws in their thinking. Why weren't they checked?
