Who do you imagine this "Linux Desktop" is, that you attribute lack of interest to?
Various groups make desktop environments that may be used on Linux, as diverse as KDE, Gnome, Chrome, and Android. It could possibly make sense to complain about one or other of them, or even several. As it is your complaint is entirely nonsensical, a category error like saying red is too hot.
Well no. The new settings panels in Windows 10 certainly do suck ass and contribute to the general UI fragmentation, but the systems that are the foundation of the Windows operating system are not disparately developed hodgepodges. The same cannot be said for Linux Desktop, although with SystemD taking over everything that might not remain true indefinitely.
