Serious question: why not, if the author just knows Rust? Are you so allergic to anything written in Rust? Then get some new pills and ointments because there's going to be more and more of it.
As a Rust developer, let me point out that this is certainly the wrong way to respond when someone criticizes or makes an observation about Rust. Especially when they aren't hostile at all. It's clear from the commenters' question that they have a some preconceptions about Rust for which they are seeking clarifications from other Rust users. This sort of response will only make them give up on Rust due to the toxicity of the community, rather than address any real issues they may be facing.
It's just wherever you go, here, Phoronix, Linux Kernel Mailing List for example, the forums are full of haters that just ask "not again, why?" anytime Rust is mentioned. Maybe I've become biased because of that.
Rust helps with performance and security, lots of examples are evidence of that. It's not 100% bulletproof, but nothing is. But it helps. And yet IT people just yell on it for some reason. Like we all should just get stuck forever with C, C++, praise Go, and hate everything else.
The antibodies are probably to the "written in rust" addendum, which seems unnecessary unless rust adds something to the product. Much of the answer above to "why Rust" concerns the developer, and we are potential customers, so who cares? Just drop the "in Rust" and don't worry going forward.
Honestly though I thought we were past the "written in Rust" phase.
It works. Including on me. I'm much more likely to pay attention to a tool that I know is written in Rust. This is both because I love the language and really enjoy using it, and because I've gotten conditioned to believing that tools written in it will be extremely robust, fast, useful, and stable. I can easily rattle off a dozen tools I use on a regular basis written in Rust that are significantly better than their non-Rust counterparts (starting with ripgrep, which is extremely fast). It's effective marketing still.
