Did you actually read the document dude? Just because one guy calls it fake doesnt mean you should accept it as such. I strongly encourage glancing through the whole thing. Low budget? Yes. Trying hard to make it look more professionally done than it is ? Yes. Fake? Not at all sure - if they did, they sure went into a whole lot of trouble to create it, and they could have done it with far less effort.

Perhaps one way to definitively prove if its fake is to take a few of the images and graphs and reverse image search it to find if their origin. Until then keep your mind open. I have seen a lot of fake shit and somehow this doesn't look like that.
