I don't claim to know much about either karaoke or rust, but from what little I know of both, that seems wrong. The Rust community expects safe code, while bad singing is expected at karaoke bars.
The comparison was about how to communicate respectfully and appropriately, not about making an perfect analogy.
Think of it this way then: it is completely possible for the Rust community to expect safe code without being entitled assholes about how they communicate that expectation.
