40 millions hits on Youtube = over $150 000 in revenu for him. I think the guy is pretty happy with its video.
Regarding the legitimacy of the video, the guy made another video on the street with a brand new phone and he bend it with ease. After seeing this I think Apple should halt production and redesign it before too many are made. Its also obvious the guy knows exactly where the weak spot is, which is not in the middle of the phone.
