Golder, I don't play the 'provide me a link to prove it' game as you are free to ignore or disregard what I have written. I don't mind as you don't know me; those on the forum who do will have already judged my experience, background and integrity.
If you are genuinely interested as to how this situation has come to pass and why F-35 is not unique in this regard you could read the US export laws on 'significant military equipment' that exist to ensure the US will retain their technological advantage. Where the US has a desire to export 'significant military equipment' to other nations and Congress consents then it has to put in place mitigation systems (eg interposer), locked-down LRUs and/or encrypted databuses and physical inspections of exported equipment and US-directed security arrangements.
No fairies will die if you don't believe me.
