Couldn't you have omitted the last two sentences, which amount to a polite version of "we've already made this and theirs only looks nicer because they spent more time?"

I suppose I could have. I've no idea how much time they spent, perhaps it was a quick hack too. It was just unexpected to see someone else's implementation of the same idea, so it made me laugh at the strange coincidences of life in general. Certainly I meant nothing ill by my comment, I apologize if it turned out mean-spirited in any way.
