How can you get so much wrong in one short post?
> Look at Microsoft. One browser. One Office suite.
Lots of browsers are used on Windows. I use LibreOffice on Windows.
> Now look at Linux. KDE vs. GNOME
Okay, that is true.
> EMACS vs. vi.
Lots of editors are used with Windows.
> BSD vs. Linux.
BSD is not Linux. It would make as much sense to claim: "MacOS vs. Windows"
> It's the Organized Religion of software, with followers locked in endless battles over which system is The One.
Hardly exclusive to Linux. There is MacOS vs. Windows, Android vs iOS, Firefox vs. Chrome, many competing applications.
> Religion never finding true peace is exactly why Linux has never found the Year of the Desktop.
No. It's all about the apps.
