Free desktop environments (KDE and GNOME, effectively) have spent a lot of time in the past ten (and more) years, first trying to catch up to Windows, then to Mac, then trying to build new paradigms, with mixed results. Some people loved them, some people hated them.
Now, having spent about half my life using, writing and contributing to FLOSS, you can’t possibly expect me to just say that Linux on the desktop is a waste of time. But at the same time I’m not delusional, and I know there are plenty of reasons to not use Linux on the desktop.
