I don't think he was being sarcastic. systemd came from Red Hat employees. It's now effectively everywhere, even in Debian and derivatives. This is not meant to be a systemd sucks rant, but if a distro is using systemd, and most do, they are using Red Hat-developed software, and a most critical piece at that. Gnome, the usual DE for enterprise Linux installs is heavily tied into systemd now. It goes on and on.
It's not in Devuan. With some community effort - that means _you_ - putting pressure on Debian to reverse their decision, it can go out of Debian, easily.
