I think blaming someone for innovating is possibly the stupidest thing one could do. dbus is awesome. Best bus we have. systemd is really nice and useful, overall a better upstart. The reason it's not a patch for upstart or sysinit is that their designs preclude certain features that systemd provides. I don't know about pulseaudio, and I'm not sold on Journal.
systemd doesn't appear to solve a problem, it seems to just add a layer of indirection and complication, as well as a single point of failure for ALL system startup services, rather than letting each service just handle it's own deal. `init` already exists to kick things off properly - now init just runs systemd which then kicks things off, for no appreciable gain.
And have you seen proper systemd integration? I installed Fedora lately, and man, that boots fast. Fedora solves so many things in a sane way that Ubuntu has been struggling since years. usplash, xsplash, splashy? Fedora has FDO's plymouth. Guess what, it works. SYS V init, the stupid Arch init, ubuntus upstart? Fedora has FDO's systemd, and it's faster than any of those.
