Let's not forget the Quora engineers are working for what is (in the very loosest sense of the word) a competitor.

If we're doing silly analogies, it's the equivalent of Starbucks sending their staff round to your new cafe with Groupons leaving no coffee or seats for the real customers and then publicly mocking your staff's incompetence in handling the situation. Sure, it's your fault for running the promotion and not buying enough coffee, but you might still consider BigCorp's behaviour a little underhand.
