I'm a lowly developer and have never even heard the debate about Helvetica. I couldn't have told you the first thing about it. It took me two slides to figure out that "the one I like" is Arial, and pick the opposite. I missed three more, but they were incredibly similar (TOYOTA, MATTEL).
Anyway, this difference is quite obvious in general, I'm not sure what the author is on about.
