The statement that xorg depends on systemd is not correct.

Here is the official reply from alanc:

shevy> Hello. Does Xorg depend on systemd?
alanc> you can build it to use systemd services or to not use them, depends on your ./configure options
shevy> ah ok so I assume that means it is optional, thanks alanc
alanc> yes
alanc> since Xorg supports many platforms on which systemd will not run


On the topic itself:

systemd does too many things at the same time.

It was not the first to break the old unix philosophy by the way, that was already broken by things like SELINUX and so forth.

There are actors at work who try to change linux into a commodity rather than a hacker OS; some reasons can be understood e. g.
to "prepare linux for the masses". In doing so, several old users will be alienated.

This happened before as well e. g. gnome3 or unity crap.

What amazes me is how quickly systemd conquered all the various distributions. It has a lot of momentum and thus will win out
simply by momentum alone.
