I'm broadly with you on disliking OP's comment because it is needlessly negative, but I don't think it quite rises to the standard of a personal attack.

Accusing the author of introducing slop into the language by coining (or using) a new term is a criticism of the author's work, not the author himself.

It's akin to saying, "Your work has a negative side effect which I don't like." Which clearly would've been the nicer way to say it.

Interpretations differ, of course. I'd say any internet comment of the form "Please $Person. For the love of god stop trying to do $bad-thing" is clearly over that line, and snarky to boot.

I know "personal attack" sounds pretty strong, but the closer one is to being the target of such an attack, the more it feels like that—and there's absolutely no need to make a point that way.
