ESR has some bits about "Learn English if you want to code" - but politics of it aside, this isn't even about coding. This is about using a plugin that someone has not signed (like, for instance, RES for Chrome which for the longest time did not have a Store entry iirc).
Why would using the lingua franca that everyone agrees on be imperialism?
We should stop self-deluding ourselves in believing that English exits in a geopolitical void. English is the language of the anglosphere, and speaking English is a huge favor to those economies, and that comes with a sense of cultural inferiority as well, in many peoples.
Aviation is a curious industry. English is commonly spoke between flight crews and ground stations world wide (with few but notable exceptions). Circumstances where the English meaning of a word wasn't well understood by the flight crew or the wrong words were spoken have, on occasion, lead to disaster--Avianca Flight 52 [1] comes to mind, among others.
I simply cannot agree that mutual intelligibility is bad simply on the merit that it somehow creates a "sense of cultural inferiority."
What I'm suggesting is that having a standard for communication is less likely to put lives at risk. I can't help but wonder if you're invoking Poe's Law by advocating from what is arguably an extremely fringe standpoint.
Otherwise, the alternative would be to require air traffic controllers to learn a dozen languages, and then you wind up with an even worse problem than having everyone settle on a single language with codified standards.
Didn't the Browser Wars teach you anything? :)
