EDIT: more specifically .. it's rather ironic how judgmental (and honestly: pretty darn pretentiously) so many here instantly get, yet how there is this implied assumption that the collective wisdom and judgement of this community is above criticism itself, somehow. It might say far more about HN, that nobody appears to be discussing the article's content itself, than it says about the (mis)use of alphabets.
I can read Cyrillic fluently, and a bit of Greek too, yet I'm not in the least bit upset about this pun. If this does upset anyone, maybe it's time for some seriously self-reflection for those people, about what they decide to get upset about and what not.
