I wonder why devs need to work on multiple different environments. I only have (user)experience with KDE and GNOME but what’s the difference between them?
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Those are all part of it, but for a broad answer, just think about any other type of software that has various alternatives. What’s the difference between web browsers? Between text editors? Email clients? Not everyone can agree on one perfect way for an app or desktop environment to be. There’s always some people who think they’d be more productive with a different design, or that a different design would be more intuitive to them, etc.
