I mostly agree with this sentiment but I think it's not that necessary to point out. Yes, some of these are abandonware but many are written by the same set of strong Rust programmers. I think you'd be hard pressed to argue that ripgrep or fd is not a valuable contribution to the OSS ecosystem.
The more interesting question is - why is that? Sure, Rust is memory safe, but I suspect the real reason people built high quality software in Rust is because cargo is good and because minimizing copies is part of the culture around the language. This means that libraries are cheap to use, and as a result programming feels productive, because you don't have a reason to reinvent the wheel (see arrays in C, or various Boost libraries that have been moved into stdlib C++). For example, compare the cost of Python's click to Rust's clap. Or look at serde.
I find it more interesting to ask the question "why do people spend so much hobby time writing interesting programs in Rust?".
