I mean to be perfectly fair, building hard dependencies on a particular init system does mean it gets way harder for anyone to use other ones, and that does suck
It's understandable that people would be frustrated by that. I've never had any issues with sysd but when I was using void I really liked runit, and with gnome increasing dependencies on systemd I'm worried I won't be able to use void anymore as a gnome user :(
Only reason I'm not using void currently is cause I'm not quite technically knowledgeable enough yet to set up and maintain a minimal distro.
The Unix principal is a thing people care about for a reason, it's a pretty core part of how this ecosystem was built up with so much user choice, and while there are some silly complaints about systemd, I do feel like I've seen some very reasonable ones. Particularly just that its a huge, very complicated implementation
