"A couple people complained about their product on twitter and they built a whole page responding to it?"

The CEO of Zendesk made the comment "@benkepes you know what they say. Imitation is the sincerest from of WAIT-WHAT-A-FREAKING-RIP-OFF! ;)"

Even if the allegation is correct, that is no way for a CEO to represent his company. Perhaps he should have contacted Freshdesk (privately) and told them if he thought there were trademark or patent issues, only bringing anything public if they refused to cooperate. If not, he probably should not have replied to the original comment at all.
