"Do you really not acknowledge the existance of FreeBSD, NetBSD, OpenBSD, AIX, Solaris, HP-UX, and more?"
Do you not acknowledge OS X, Windows, BeOS, C-64 DOS, CP/M, PS/2, VMS, MVS, Amiga DOS, Apple DOS, etc.!!!!?????
I guess you don't get that there are lots and lots of OSes that aren't Linux, and trying to be one system to rule them all is a fools errand? Again, you don't know anything about software engineering so stop complaining when the people who do make the right choice. When I said systemd is universal that means in a Linux conext, and your attempts to paint it as otherwise are not "cute" or "insightful".
" Just because something does the job and hasn't been mucked with in years does not mean it should be presumed garbage and replaced."
Your statement shows how much you don't know about init systems. every init system has been mucked with constantly. Again, your delusion that there is a single (or even two) init systems that "haven't been mucked with" blasts your complete lack of understanding of init systems to the world at high volume (and the bass is way to frigging loud.)
