The F-35 is highly politicized, and that political fight takes place on the battlefield of public opinion, with both sides trying to manipulate the public with propaganda. And many here on HN are playing their roles perfectly, responding to the propaganda like mice responding to stimuli in a maze.
We're all susceptable to it and I try hard to learn to recognize it. I think a good sign of propaganda is the choice of phrasing. If someone is trying to manipulate you, they often try to arouse anger and outrage -- angry people aren't open to reasonable discussion and other opinions, so if you get people outraged on your side then they are innoculated against other arguments. You can see the lack of balanced, smart analysis and the widespread expression of outrage here. Someone trying to inform you will take a much different approach, carefully presenting information and avoiding distorting your understanding with provocation. For example, consider the phrase, "New stealth fighter is dead meat in an air battle" -- clearly it's meant to arouse and not inform.
The article represents the analysis, abridged and without context, of one tester in one test of a system that's in its test phase and not meant to be in production for 1.5 years. There are many other articles, representing individuals' opinions (including test pilots), some that praise the F-35 and some that criticize it.
I'm not saying the F-35 is a good deal; I don't know. I don't know much at all about fighter planes (and reading the comments, I know more than many here). I don't know if dog-fighting is relevant; maybe it's gone the way of broadsides in combat between warships (and better dog-fighters are like Henry Ford's 'faster horses'). I don't know if the problems described by the test pilot are bugs of a test system (that's why we test!). Think about the state of your systems 1.5 years before production -- they may not look so great.
I do know that propaganda like the OP reduces public knowledge; it doesn't increase it.
