Some people do it for the attention, some people do it so they can point a finger in another video on another youtube account and discount it, some people do it in the hope someone will message them for plans or offer to pay for their research. There are any number of reasons why the person made a video like this, but what is certain is that he did make the video, and it is totally misleading if not an outright lie. To go through all the trouble there must be some reason.
