Most people talking about C# and Java, they refer mostly to application development. You rarely hear these languages at system programming (doable, just rare). Rust is at C/C++ level when it comes to system programming and eliminates a lot of C/C++ issues and yet added features found in Java and C#, and even Haskell. People just don't know a lot about Rust to criticize upon and yet seeing it mentioned everywhere. I can understand if some feel a bit "fed-up" seeing Rust brought up in a non-Rust thread. But I do agree with you, Rust is very relevant for discussion here.
