Ken, pardon my ignorance if I have misunderstood your quote but, are you actually saying that the reason the F-35 is so flawed, is actually down to the customer/'s who issued the contract and specs, rather than LM for failing to meet them, or saying they couldn't actually be met?
Is LM failing to meet the requirements? With very few exceptions, no. Have the requirements shifted nearly constantly? Yes. LM cannot change the requirements. The governments running the program can. And have.
And finally "so flawed?". What makes you believe it is "so flawed?"
