I closed that thread, the maturity level in there is... highly variable. There's a lot of kneejerk statements in there.

Meanwhile, this decision was made or led by one of the few people that developed multiple popular programming languages. I trust his opinion / decision more than internet commenters, including my own.

I am not sure if we see the same thread. There is one reaction from "Rust" dev (who seems have a very new account on github) on why not rust. Most of the others seem to be from C# side. The pattern also seems to be the same on reddit thread. There is one post about why not rust, equally (or more depending how you weigh) is how other people react to this news.

What is weird is how much people talk about how other people react. Modern social media is weird
