You're seemingly clutching at straws. I'm not a fan of Ashtons personality, he has ego issues and his framing wasn't great, but he absolutely said he would sign an affidavit and provide a bunch of evidence and kim was going to pay him in crypto, whether or not this was incentive, the point is he never signed anything and then conveniently stepped out of the picture.
It's would be exponentially easier to lie about and forge two photos than it would be to fabricate the videos. The only person who tried to claim he made them was caught lying about it.
Consensus fallacies are just cope at this point. Most people believe it's possible to have made those videos, when it isn't, and the little details that wouldn't be known to the public only make a stronger case for authenticity.
