TwinAisle cites Private Eye's article, and says "clearly there are elements that don't add up".
There are two major points that "don't add up".
First, the article asserts that FBW systems before the B777 were triple-redundant, designed/written/implemented by three separate teams. That is rubbish.
Second, the article concentrates on the PFC (and maybe on the AIMS). I don't think anybody has suggested there was something wrong with primary flight control.
