So you prefer to force your crap onto others, of course.

Server or desktop, the hardware and the kernel are entirely event-based
now. This is important for the network, and it is even more important
for the boot system. It’s not a question of changing configuration files
or whatnot, it’s a question of having it working, and working reliably.

Indeed. This is why we only install one desktop environment at a time.
We even ship different CD images for that purpose. As for text editors,
I’m the first one to say we have gazillions of useless ones, and merely
a handful that are actually useful.
Still, it is way easier to switch a desktop environment or a text editor
than to switch init systems. And it’s more useful, since different
desktop environments or text editors have different sets of user-visible
features. An init system is not something for the user to see, it should
just do the job properly.
If you want a more suitable comparison, supporting two init systems
would be like supporting two packaging formats. It means more work for
all maintainers to support all possible combinations, and it doesn’t
change anything for end users.

That’s because init scripts are full of hacks to work around its
deficiencies, thanks to tireless tuning work from the maintainers. And
even with these hacks, you can always meet a condition (hardware
combination, complex partitioning scheme, network configuration) for
which it will not work, or - even worse - work randomly.
