I don't understand how it's off topic? It was a reply to someone asking if Linus would write his own init (because he's unhappy in systemd), and my take that it would be a bad idea because of the usability issues in the last big thing he started.

It's off topic because (a) the subthread became about Git usability, which is not the topic and (b) it's one of those subjects that quickly sucks the oxygen out of other discussions. Not nearly as badly as systemd of course, but still.
