You're doing the thing he was trying to avoid. You want to have a discussion about this hypothetical emoji and make a bunch of statements about the psychology of the person who doesn't want to waste his life on it. Nothing like being accused of not liking "fun" when you don't want to do something useless at work.

Maybe not everybody likes goofy emojis, or Harry Potter references, or whatever easy nothing passes as wit for some people, and they think it makes everything less professional and introduces unnecessary maintenance. Those people have to make the choice to shut up about it, or mention it and have somebody tell them they're joyless.

edit: irt 418, it's historical and it has already imposed most of its maintenance burden. But using it when you're not a teapot is forcing the meme.
