Inverse Occam's Razor

 There are are a number of news stories about right wing, anti-vaccine, COVID deniers claiming that their illness after attending maskless, anti-vaccine mandate rallies was due not to contacting the virus, but instead was due to a deep state bio-attack.  (Sample story: https://www.thedailybeast.com/far-right-stars-joe-oltmann-jovan-pulitzer-fantasize-theyve-been-attacked-with-anthrax)

I asked one of the Philosophy prof I know to ask if philosophers had a term equivalent to an inverse of Occam's Razor.  The answer was in light of the current environment there was a lot of discussion of the phenomenon, but no, there was no existing expression.
