I think you're eliding a lot of context here. Specifically the context of overzealous Rust fans. There's a strong, though not universal or even majority sentiment that "writing anything in C or C++ is basically the same as committing assault, murder, professional malpractice or other similar hyperbolic claim" that some Rust advocates engage in.

There's a whole meme about the "Rust Evangelism Strikeforce" on n-gate.com for a reason, and that reason is the community on HN has become a caricature of itself.

By the way, this is from a person who made a point to introduce Rust to the team, when even just a year or so ago I'd have preferred C++.
