The truth is that FreeBSD doesn't want casual users, though.

The Linux (Ubuntu, etc) install experience leads to a usable desktop. Heck, the installer disc boots to a usable desktop.

Also no unsophisticated users even know the name of their favorite DE. Or what a DE is.

Requiring a text login and a shell command, even one as simple as "pkg install KDE" is a big ask for a casual user these days. Also, that command line will probably fail. :)

I write these things as a very big fan of FreeBSD! I think not catering to casual users keeps FreeBSD in a better technical place overall, but Linux is obviously much more popular. This carries risks too.
