That's an interesting, well sourced article, I'm glad I've read it. I honestly didn't know that the full-size straw-airplanes were fakes from a movie. They're the face of this metaphor.

That said, the article would have been a lot better without moralizing about harmful colonialism, or claiming that this metaphor is supposedly an insult.

The purpose of this metaphor was never to gain historical insights, or to teach a lesson about colonialism, or to judge the Polynesian natives from 80 years ago, it's to teach a lesson about modern practices of software development (or science I guess). It's a fable.

You can replace the Polynesians in the fable with anyone else, and the payload of the fable does not change. Because the payload of it has nothing to do with the Polynesians. I personally didn't remember that this metaphor was specifically about Polynesians and the war supplies. I remembered it being about some abstract tribes, possibly Africans and humanitarian aid supplies. Did someone explain it to me the wrong way, or was it me who assumed wrong from the fake photos? I dunno. It does not matter. I wasn't relying on this fable for anything other than a software development lesson. It was not a covert tool to justify colonialism, or to assert intellectual superiority over some historical tribes on the other side of the globe.

It's definitely good to know the historical truth – as I said, I genuinely do appreciate all the exposition in this article. But, if you package that together with the moralizing, it comes off as yet more culture war BS that I am so sick of.

The difference in motivation is very important. If you write with the primary goal to expose historical inaccuracies – that's great. Then I can trust you. But if you write with the primary goal to stop people from using offensive (in your view) metaphors, then the historical inaccuracies are just a convenient tool, a talking point, for you to achieve your real goal. Because if this metaphor was actually historically true, you would probably still find it offensive. And so if that's your goal, then I can't trust you to provide historical accuracy. I will suspect you of presenting selective evidence, and other tricks to further your goal. That is why your moralizing detracts from the article.
