All that systemd demands of system administrators is that they take some time to learn an excellent new piece of software instead of spewing a knee-jerk reaction of "get off my lawn".
At this point in time, I count Pulseaudio and systemd amongst the best pieces of software written for Linux. The no. of features that they expose to ordinary users and sysadmins is staggering—and they do this without removing features or functionality, and while maintaining near-perfect backward-compatibility. I'm shocked that no one realises how hard it is to do this, and what value these add to our ecosystem.
At this point, after dozens of blog posts by Lennart explaining systemd, if I see anyone arguing the way you are, I am compelled to conclude that they never really gave systemd a fair chance; or, worse, they're too angry at its very existence to even try that.
I feel like most of the animosity towards these projects is not because of their (perceived) lack of technical merit, but because of the abrasive personality of their creator.
