systemd tries to unify a Wild West situation where everyone, their crazy uncle, and their shotgun-dual-wielding Grandma has a different set of boot-time scripts. Instead of custom 200-line shell scripts now you have a standard simple syntax that takes 5 minutes to learn.
Downside is now certain complicated stuff that was 1 line need multiple files worth of workarounds to work. Additionally, any custom scripts need to be rewritten as a systemd service (assuming you don't use the compat mode).
People are angry that it's not the same as before and they need to rewrite any custom tweaks they have. It's like learning to drive manual for years, wonder why the heck there is a need for auto, then realizing nobody is producing manual cars anymore.
There is also the argument that it's more complicated under the hood and harder to troubleshoot, particularly because of it's inherent parallelism and dependency-tree design, whereas initv was inherently serial. It was much more straightforward to pick the order in which services started and shut down on an initv system.
For example, say I write a service and I want it to always be the first service stopped during a shutdown, and I want all other services to wait for it to stop before shutting down. That was trivial to do on an initv system, it's basically impossible on systemd.
For those wondering, yes I did run into this situation. My solution was clobbering the shutdown, poweroff, and restart binaries with scripts earlier in path search that stop my service, verify that they're stopped, and then hook back to systemd to do the power event.
I had numerous situations where systemd didn't let me abort a hanging service startup during boot or stop during shutdown.
So what do I do now, systemd? Wait till infinity??
That never happened while using other init systems. Because they simply fail properly ("sorry I did my best to stop this, I needed a SIGKILL finally"). Or simply let me log in: "sorry, some services failed to start and now it's a huge mess, but at least you can log in and fix it.".
