First, I feel the implication that "if you aren't reassured is only because you're dumb" is unwarranted.
With that out of the way, being expensive does not preclude shoddy work. At the end of the day, the only difference between "they are so concerned about security that they are willing to lose millions[1]" and "their process must be so bad that they have no other choice but to lose millions before their death trap cost them ten times that" is how good your previous perception of their airplanes is.
I think that, had this exact same issue happened to Boeing, we would be having a very different conversation. As the current top-comment suggests, it would probably be less "these things happen" and more "they cheapened out on the ECC".
