Your comment spawned a generic flamewar-style tangent that lowered the discussion quality enough that we got email complaints about it.
Btw, the site guidelines also include "Don't be snarky." - I realize that takes some of the fun out of posting a particular kind of comment, but people tend to overrate the quality of what they post when they post that way, and tend to underrate the degrading effect it has on discussions, and that's a double whammy of badness. Having a don't-be-snarky rule, and sticking to it, is a way of globally optimizing for fun—specifically the fun of interesting, curious discussion. That's more important than the sugar rush of being "cheeky".
