You're thinking about his
first video on the game where he theorized it was based on a real life Chuckie Cheese shooting, Man, nine years ago, time flies. Anyway I don't hate this, its an attempt to engage with the game on a non-literal level which he used to do a lot more often. Scott did say it was bunk, but he wasn't mean about it, just that the game wasn't based on any real-life events. You might be confusing this for his
Petscop video where he, or more realistically someone on his team, compared the game to the real-life tragedy of Candance Newmaker. The creator went off on him on Twitter and was angry and horrified that Matpat was comparing the game to anything irl.
