It works but so do the others. I still maintain a sysvinit machine and it works just fine. This cartoon is just another example of someone who picked their team and now hates all the other teams. Someone who thinks anyone who thinks differently from them is stupid. Or they are just another troll.
I don't like systemd on the meta level but I must admit that it's quite pleasant to use. So I'm not quite on the fence about it but rather of the opinion that both camps are correct in their own way.

False. All the other teams are varying degrees of well-built. Systemd is badly-built by bad people and pushed via market dominance. It's the Internet Explorer of inits.
