Void Linux uses runit, for example. Here's the documentation they provide on how to use it: https://docs.voidlinux.org/config/services/index.html
It only takes 5-10 minutes to read and understand how to manage all your services and write your own. Simple and fast. If only systemd were this easy!
It's really annoying. It no different from people who go into Linux forums and talk about how much they love Windows.
