How is it someone's else's fault for that systemd has dependencies or that others depend on systemd?

If I use and like Firefox, and others depend on Firefox, or Firefox depend on others, then it's Firefox fault for you choosing Firefox?

I really don't understand the argument you're trying to make. You had choices before systemd, and you still have choices even though systemd is widespread, what's the problem? It isn't modular enough? Use something else then that is modular.
