It's not about Upwork intentionally skewing the results as you pointed out, but that there is a potentially sampling bias. Upwork might only attract certain kinds of programming jobs and those are less likely to use Go and Rust.

Except it doesn't work like that at all. In there you have real problems from real people who want the job done. If their problem requires Rust, then trust me, they will ask for Rust. And those are the people who pay the freelancers. As a freelancer I have zero saying in what clients want, I am there to help with their problems, not for them to bow before my choice of programming languages.
