There are a lot of obsessive people on Wikipedia. Back in the days when I was an active editor, I was regularly embroiled in edit wars with somebody who had odd but extremely firm opinions about the romanization of Okinawan (not a political topic even in Japan) and what appeared to be 24/7 ability to enforce them. I suspect quite a few of those shut-in "hikikomori" types are top Wikipedia editors...
All that said, checking the manual of style in question today, I'm positively surprised to see the weirdness is gone. This is a strength of Wikipedia: over time entropy of opinion tends to decrease, even though it may take years.
