^If they're Apple Developers, they know very well that Apple rarely responds to criticism -and does not respond to threats at all. Especially from their 'partners.'
Besides, how can you possibly shame something ad shameless as Apple and Steve Jobs? Their only response to criticism (when they respond at all) has been to play the victim and accuse their critics of "not getting it." Translated into English, that means "you're stupid."
But most times they don't even do that much. Apple's usual responses are character assasination, sarcasm, and snide remarks intended to amuse their fanboys.
I think the posting was just a statement of genuine frustration and an attempt to keep their customers updated on why the new version has been stalled.
