They do this for getting higher ranks here at hackernews. What turns me off most is that they succeed, which in turn indicates that large parts of hackernews readers are biased towards Rust. Personally, I'm pretty sick of this evangelism and hype because I fell for it some years ago and started a project with Rust. Countless problems and dark corners. I moved in time to a mature garbage collected language. There's a reason Rust has kind of succeeded only in small niches where Rust is a good fit. And not everywhere (backend services, CLIs), like it was advertised by prominent evangelists.

However, for System 76 Rust is a very good choice.

But calling it "Rust based" when it's GTK is clearly a bit bold ...
