This is far from true, lmao. It's only tightly coupled to depending on the Linux kernel. systemd was in fact heavily inspired by MacOS's launchd. At worst, it can be said that complex boot managers will begin to converge on a design that actually works ~ MacOS did, Windows did, and now Linux has with systemd. The three have plenty of differences, though systemd is still closer to launchd than not. And in actuality, it's very tweakable. Did you notice that the source code is open, for a start...?
