Well I don't think it's childish - the car wasn't exactly "complete" in those photos so I can understand why someone would want to keep that under wraps. Remember what happened the last time pictures like that came through here.
In the end, I think it serves the greater good to respect someone's wishes in a situation like this. It's not like the pics were taken randomly in a public location. Someone just didn't get the message that if they were allowed to take pictures that they were not supposed to be broadcast around the web.
