No.
You can disagree, but you cant deny the fact that, out of the box, its familiar to 99% of users coming from windows. It has a taskbar at the bottom and "start menu" on the left. It has desktop icons and its own suite of applications. That initial impression to someone coming from windows is very important. It needs to be somewhat familiar environment that is easy to understand and grasp by non technical person.
To me personally, KDE is the worst desktop environment ever created and i would never use it. But im more than capable of understanding why it was chosen as default. Its a strategic decission. Not technical.
If you dont use KDE, why worry ? There are non systemd linux distros out there that use elogind to run desktop environments that require systemd. I see no issue of doing the same on FreeBSD.
If it ever comes to that, they can always switch to Cinnamon or XFCE. I really dont understand the fuss about all this. People are behaving like KDE is forced down our throats with no option to use anything else. As long as you have the option to install minimal version of FreeBSD, i absolutely see no problem.
