It's good to interrogate the wallpaper of colonialism, to discover what's hiding behind our euphemisms and clichés.
The phrase "cargo cult" as I had come to understand it before reading this article, definitely centered the cult's naivete ("oh those silly cargo cultists, worshipping shipping containers!"
But reading this passage:
> Other natives believed that God lived in Heaven, which was in the clouds and reachable by ladder from Sydney, Australia. God, along with the ancestors, created cargo in Heaven—"tinned meat, bags of rice, steel tools, cotton cloth, tinned tobacco, and a machine for making electric light"—which would be flown from Sydney and delivered to the natives, who thus needed to clear an airstrip
clarifies that this "naivete" was cultivated, by settlers with ulterior motives.
Using the idiom uncritically elides this dynamic, laundering the practices of missionaries that I'm sure most people here would loathe to be on the receiving end of.
Knowing this enriches the analogy when using it to describe aws lambda or whatever people use it for ("Who is producing the cargo? What are their motives? Why does one group have power over another?") but I think, in general, it would be good for people to find additional ways of talking about dynamics where people are making choices out of ignorance.
Because even if you don't agree with my social justice bent, I think Orwell was on the right track to say "never use a metaphor, simile, or other figure of speech which you are used to seeing in print."
