I'm not sure it's really a bashing. I read it as he's glad after all that facebook didn't hire him, so it's more like a message for those who already "lost" or will "lose" in puzzle-based hiring process. A message that states it's not necessarily their (i.e. prospective employees) loss in the end, and the more important part that it's not a reason they should feel bad about themselves after such "loss", because solving riddles is about solving riddles and not about finding good programmers (being one doesn't necessarily exclude having puzzle-solving ability, but it's not like a symmetric difference of these sets is empty, really, more like quite voluminous, I would say).
