I thought he was very unprofessional in the way he handled things. Cursing usually gets you no where when trying to make a coherent point.
I don't think has anything to do with professionalism. He was complaining to his adoring fans which expect Trent to be edgy and speak his mind. I'm sure he didn't email Apple cursing them up and down the street.
We macrumors and other rumor sites are the ones that blew it out of proportion. It was basically him talking to a friend, whom in turn talked to another friend...
