I've been paid to write software in C, Java, Python, C#, Perl, PHP, Bourne shell, and doubtless many more I've forgotten over decades.
If you consider "People who use Free Software" to be users you can doubtless add a dozen more languages, including (which was a surprise to me 25+ years later) Scheme apparently, but most recently only Rust because that's what I'd prefer to write. If you've used Rust's compiler, a tiny portion of that was written by me.
