To be fair, he has been right about weirder FNaF-related stuff ebfore as per confirmed by Scott himself, so I would not discard that theory outright just yet. Whether or not he is right because he deducted clues correctly or because Scott was like "Hahah, yeah, that's it… hah" after finding a giant loophole on his own story better explained by a theory asspull is another topic.

I hate it because some proof he said like "Freddy could see through walls and Gregory looked different" no shit, people have organs, yet I know some part will be true
