You have asserted that systemd is "written and designed by people completely disconnected from the user". This is not true at all. The systemd people most definitely use systemd. In fact, I am hard pressed to think of any system or service management toolset where its authors were not also some of its users.

Moreover, the headlined article is talking about graphical user interface design, something which is largely inapplicable to systemd, and to system/service management toolsets in general.
