The whistleblowers handwave itself fails because it assumes NASA didn't have any oversight over the production process. They just allegedly told these special and visual effects people to make the most convincing and large scale effects of their life, lie to the general public and not even be able to take credit for it, and NASA didn't have some trusted scientists and engineers to go over the produced material? And if all these people, including those on oversight, were so guilty about faking it as to add these details that, if truly evidence of a hoax, would be incredibly obvious, why haven't anyone come forward?
