You're making an assumption that Ibaka intentionally hit Griffin in the nuts. To me, the video proves otherwise. The most logical explanation for Ibaka's hack was a move to free Griffin's grasp from his jersey. Clearly, Griffin is just man handling Ibaka via his jersey..which is cheap. Any player is gonna do one of two things - go to the floor to try and get a foul call on Griffin, or do something to get the guy's damn grasp away from your jersey. Ibaka did that, which to me is manning up to the situation rather than flopping, which is what Griffin woulda done if the situation was reversed.
