If you are to just claim that someone made something up, you must yourself raise the standard and provide a scientific or otherwise evidential source. And Vice ain't it.
Vice in this article links to evidential sources while summarizing the findings. You should bother reading it and what it links to.
ALSO, and this is a bug fucking also, that's not how the burden of evidence for claims works! You just argued against falsifiability! OP is responsible for providing evidence for their own made up claim!
The burden of proof is always on the person making an assertion or proposition. When they do not provide proof of their claim, and another person calls it "full of shit", it is not valid to shift the burden of proof onto them to disprove the original claim.
And there's a great reason for this - the bullshit asymmetry principle: the amount of energy needed to refute bullshit is an order of magnitude bigger than to produce it.
