dbus is NOT a desktop daemon. This is very important, and that single
misunderstanding is probably behind all the fud you read about it.

dbus implements a message bus - an amazingly useful thing to have.

Why do you need or want a message bus?

You might as well ask why do you need or want any other form of IPC you
already have, as that is what dbus is. It's a very small, light daemon,
can run system-wide or per-session and has the potential to many of the
IPC implementations you already have. Those are the ones that don't
happen to show up in ps so you hear very little whinging about them.

That desktop systems are the main user of dbus at this point in time
doesn't change one bit what dbus is designed to do and it's usefulness.
