You mean the other chat apps, right? Or do they do something other than chat as well? In any case I'm not sure if I'd call their iMessage thing a PR stunt (okay, the tweets were likely PR), I'm just happy they support as many standards as they can. (I'm also not sure if my original comment was seen as wrong or controversial judging by the downvote)
