The fact that you're mentioning launchd in the same breath as systemd and upstart suggests that you don't actually know a lot about the situation. launchd is a Mac OS X init equivalent. It has never, to the best of my knowledge, been ported to Linux at all.
The article's not particularly accurate on that note. There is a project to port launchd to FreeBSD, but it's basically stalled: no commits or mailing list posts in over a month, and it's not clear that it's even been successfully compiled on FreeBSD yet.

You didn't read the article. Launchd is being ported to BSD. If you knew anything about about any of these inits you would see their similarities.
