That is an outrageous comment. Most everyday users who would be the type that would need to move to Linux for it to actually gain real growth against Windows don't even know what systemd is. Most of the squabbling over it comes from Linux insiders, who if they wanted to could simply tailor Debian to use their own init system, so if they dont like systemd, why dont they just put in their own init program after they install debian?. As far as I know, there is no reason why the distribution should not allow the user to select another init system, other than the default systemd. You could also configure systemd to start up your own init scripts and programs and start your programs from those scripts.
Furthermore most of the squabbling over systemd seems to be about the fact that some people do not like that systemd gives you more control and flexibility over the startup process. It seems as this group is opposed to anything that would extend or improve upon Linux's mechanisms that would allow for more options and control. They are opposed to being able to start a program on the NIC coming online, if that is what you need to do. systemd does not take away any functionality, it fully supports the full SysV init system, so its not as if systemd is taking away your ability to set up your init system like you always have. All of the functionality it adds is in addition to the existing functionality of previous init systems. What this means is that those who oppose systemd are only about taking away choice, control and flexibility from other users, they do not want other users to be able to utilize certain features. So these people basically want to keep Linux difficult to use, unconfigurable and inflexible. In fact, those who suffer and lose the most from the attacks on systemd are techie types who can most benefit from the kinds of control and customizability that systemd can provide in initialization and system control. I believe that many of those who oppose systemd are in fact agents of Microsoft trying to undermine Linux and attack anything that could actually make it better.
