I understand what and why are you saying that. But I don't think it would be polite at all to rough the author up. Considering the time that (s)he took to write this down and decided to shared with the world.

Sorry, but it sounded really weird to me to ask for politeness in this context. What I would do is suggesting the change of format, or even better do it by myself if that would be bothering me that badly. Just saying...
