I think you are overreacting to the phrase 'battle-tested.' Its a commonly used phrase that does not mean specifically someone who has been in an actual war. It just means they have real world experience. We say things like, 'that teacher has been battle tested in the Public school system,' or 'that broker has been battle tested through good and bad markets.' Its a common American English usage.
As to the rest of your post, I think you are over reacting there too. It actually summarizes a very old debate. The original poster is NOT in fact the first person to make the statement, 'an American company errs on the side of individual freedom while a European company is more inclined to favor an approach that relies on systems' - it cuts to the very essence of the debate. Just google 'Fly-by-wire vs computer controlled debate'. You will find numerous references to the cultural differences that drive both philosophies - by member of the aviation industry on both sides of the Atlantic.
What is interesting is your comment that 'the answer is statistics' - both sides use statistics to support their argument.
