I call bull. The Petscop creepypasta creator didn't confirm or deny the theory until later on when he apologized for putting in the references since it got Matpat cancelled. This has very obviously taken inspiration. I'm not condemning it for that (that whole sitch was dumb and a little too woke for me, plenty of fictional works have taken inspo from real life tragedies and it's called art, prudes) I just think he's lying about it to cover his ass
