The reason this person is getting downvoted with no answer to their good points is an indicator as to why the subject is sensible.


Someone (admittably an asshole) found how to solve a problem, wrote a suite that does a very good job where the alternatives were absolute crap, and all major distros started using it.


Everybody is free to write another alternative, but everybody that is capable knows that systemd is probably better than whatever they could make, so that is what almost everybody is using.
