I don't even see what's so bad about this. Someone made a ridiculous statement in an assholish way, and the company responded in kind. We are past the point where people and even companies are expected to keep a sense of civility at all times. Especially companies who mainly cater to the younger demographic (I don't see stuffy old people buying Coconut Water).
Also this. The Internet is a Pandora's box that unleashed the worst social behavior of mankind that is now free to flow and flourish in an environment perfectly suited to it's existence and continued growth.
