You're moving the goalposts.
You started at
> it's fairly common knowledge that the Rust community leadership regards all other programming languages as existing in an adversarial, finite-sum outcome space with any remotely adjacent programming languages and regard it's elimination of other language use as a first-order good.
and now arrived at "there's a subreddit, a glossary entry for a meme and a blogpost complaining of the years defunct core team". Note that the complaints on that blogpost have nothing to do with what you're concerned about.
> Like I took a bunch of fucking mescaline and imagined a world where the Rust community is actively trying to get things rewritten in Rust, get the DoD to mandate Rust for whole classes of taxpayer funded software, the groups at the FAANGs doing strategic rewrites of like revision control systems that worked fine, the whole thing?
You seem to be conflating "projects using or recommending Rust" with "a grand conspiracy of a shadowy cabal of Rust people getting their way, all the way to the top of the US government".
I'll restart my claim: no one in leadership can be quoted saying that people should only use Rust everywhere. I'll go as far as saying that it's unlikely anyone that has a commit in rust-lang/rust (a much lower bar) can either.
