Went down the rabbit hole a bit (thanks Google) and found this thread from 2003 where someone said "real men use vi".
https://www.redhat.com/archives/redhat-install-list/2003-Jul... I take it to mean real men do difficult things for no reason, which is not really a positive thing. A 2008 article updated the phrase to "real men and women use vi", still as hyperbole.
http://www.terminally-incoherent.com/blog/2008/10/01/vim-tip... I guess the posted article didn't get the memo and still used the men-only version in 2011. But I guess you're right about this particular article, it's too easy to read it "straight".
