Could you point me at the members of the Rust project doing so? I'd want to have a word with them (I'm a member of t-compiler).
The most toxic Rust leaders exited from the project a few years back, though some are flaming more freely than ever, e.g., Go barely deserves to exist, “SQlite is a terrible example” etc
(And it's entirely possible it was back when I ONLY saved a copy of articles of that tier of "I may need this again" via ScrapBook/WebScrapBook, I haven't yet set up the browser/indexer for those and a few quick ripgrep searches aren't turning it up.)
I believe it had something to do with the JVM having some flawed semantics which couldn't be fixed without breaking compatibility with existing bytecode.
