> Maybe "Rust" in the title helps, maybe it doesn't. Clearly HN doesn't like it and that's okay

HN definitely likes it, when it is used in the correct context. Using Rust in the title is a soft promise for better reliability and quality for the software than on average. But it starts to get controversial when Rust is not purely the controlling part of the software anymore. So people start to complain because it can be misleading marketing which is based on the promise that Rust can offer.
