> The Go choice over Rust/C# reveals something deeper: Microsoft prioritized shipping a working solution over language politics. Go's simplicity (compared to Rust) and deployment model (compared to C#) won the day.

I'm not sure that this is particularly accurate for the Rust case. The goal of this project was to perform a 1:1 port from TypeScript to a faster language. The existing codebase assumes a garbage collector so Rust is not really a realistic option here. I would bet they picked GCed languages only.
