Nothing there supports there were a significant number / more than a minority of people against systemd in Debian outside Ubuntu, which was the extraordinary claim I was (implicitly) complaining against.
I see the convincing arguments against systemd, mostly wrt to the support of the FreeBSD kernel in Debian. I wasn't familiar with them, it's interesting, thanks.
