What's this weird capitalization?

Lennart gets pissy about spelling. https://www.freedesktop.org/wiki/Software/systemd/

Oh, and yea, systemd depends on dbus, not the other way around. (one of the dumbest decisions in the whole thing, if you ask me)

Some of that sounds like he's having a bit of fun, not sure if I'm mistaken though

What that dbus doesn't depend on systemd? It's good that it doesn't because people that don't run Linux want to use it.
