The short answer is: it depends on what you’re doing.

Most servers run on Linux, so anything related with web backends or high performance computing (rendering, complex algorithms) will likely be deployed on Linux in production, so the devs may choose to do the whole program lifecycle from there (even if the language/framework is OS agnostic and could be developed from anywhere).

Other kinds of programs like video games may need a windows for their entire lifecycle, and iOS apps need macOS.

There is likely no “need” to develop from Linux, and it’s not necessary better, but some people may choose it for the entire lifecycle anyway
