I get where you're coming from, but you have to realize, this guy is a new grad and he's probably pretty scared about which path to take because he doesn't understand the long term implications. He went to quota to discuss it with people and try to figure things out.
It seemed pretty obvious to me that the guy was just trying to make the best decision for himself. The right thing would have been for the CEO to let the guy talk it out and come to the conclusion that Zenefits would be the best opportunity for him, not to attack him publicly for trying to figure out the best career path.
