Perhaps if you weren't spreading misinformation, we wouldn't be

None of this is true.  It's true that systemd uses some Linux-only
features like cgroups, but I was using those features well before
systemd came around.  And firewalld uses Linux only specific features
too -- it manages the NETFILTER rules which is a linux-specific
project.  The only thing that seems to be in common is that they are
both projects that end with 'd'.  I suppose you're going to start
claiming that SSHd, HTTPd and NTPd are up to no good.

There was already a move away from SysV init before systemd was
introduced, heck RHEL6/CentOS6 used Upstart instead of SysV.  There
are always going to be projects with a diverse set of tools, it just
depends on how many people care about it.  Turns out, not that many
people care about maintaining a SysV init (or other init) distro.
