If that is the case, then I do not really see the point with this question, since it is far more interesting to know the percentage of Linux developers than what particular distro they use. It becomes a comparison of apples and oranges.
Rust is in the top when it comes to most loved languages.
I also note that they claim Windows is the most used OS, but when you summarize the different Linux distros, then Linux is more used professionally and almost as popular for Personal use.
