By the way, from the link that the OzTroll supplies:
Three questions that all those export customers should answer to their voters: In what Block will those magic cyber capabilities appear? What guarantees have been provided that F-35 cyber weapons developed by the U.S. will be shared with non-U.S. operators? And, failing that, will international partners be enabled to program their own cyber-operations tools into the F-35?
We seem to have seen answers to those questions recently.
