I also use hyperbole as a rhetoric instrument but in text seldom works.
Again, much like Windows and other MS products. People effectively had to use them ("well technically they could quit their jobs instead, so they didn't really have to"—LOL), which sets up circumstances for some serious hate. To repeat what I've written elsewhere, no-one is upset with any other init system or audio daemon creators, even if they don't like the software. Something different happened with these projects.
There are jobs which force you to use Linux, and SystemD in particular? Where do I sign up?
If you cannot switch the distro, then you deal with it. That's the tyranny of not using Linux-From-Scratch. But that's always been the case; the distro maintainer make the decision what to package and what not. It's not different with the service manager systemd.

Ever wondered why? Because it is vastly more simple an implementation target than writing bash scripts. It's more easily tested in isolation and the documentation is outstanding.

Oh, I remember the heat and hate that Ubuntu got when they switched to Upstart. The reason that systemd gets all the rage is because it is the largest target with the most innovation. People always get mad when things change. People *hate* change.

Pulseaudio had to plow the way and thus got all the heat for exposing tons of bugs in the alsa kernel drivers. And what else is there besides pulseaudio? PipeWire? This is the successor to pulseaudio, the next iteration.

Which is...?
