Occam's razor is easy to misapply. All you have to do is make the wrong assumptions. You seem to be assuming that there is no good motivation to create at least three different fraudulent things. I can think of several good motivations by several different actors capable of doing so, both white hats and black hats.

Regardless, I have seen two different video angles. This picture means nothing to me. This picture is not a video and his hands are not on top of the microphones in it. I have no idea when or where this was taken, or even if it was taken at all (faked).

In both videos it is very clear to me that the perspective of his hands relative to the microphones is completely wrong. His hand, if they were indeed going over the top of a close microphone should look like it gets bigger. That is not what happens. Perspective is all wrong. There are also numerous screen artifacts that suggest green screen. I have seen past videos that I know are one way or another that corroborate these statements.

Everything about both videos is wrong. Using Occam's razor to prove it wasn't wrong is a misapplication imo, because it is based on an assumption I disagree with. Even if it wasn't though, Occam's Razor is a guideline, not a rule. In reality it often turns out to be wrong.
