Quoted from Rarehero:

He didn’t say “one” thing...he’s just a constant shit-stirrer in the hobby...and I say this as a friend & a guest on the show.
If we wanna play “who done it”, we have to examine motives. Who’s he pissed off?
-Stern generally hates him. He talks shit about their playfields, their BOM cost, he’s “ruined” 2 of their launches by releasing info & pics early, makes fun of Zach Sharpe, talks shit about Dwight, etc.
-Deep Root - he recently did a story about Barry Oursler’s blackface Halloween photo, and leaked a pic of their cabinet design until he had to take it down after DR threatened him.
-JJP - He was their guest of honor and got the Wonka VIP tour, only to turn on the game and shit on it...been talking lots of shit about Lawlor & all the JJP behind the scenes drama...teasing GnR with mini leaks.
...or, could it just have been some random hobbyist/listener who didn’t like something he said?

Quoted from flynnibus:

It was more about the self proclaimed expert and champion of the hobby... who he himself didn't actually know anything about it and when he tried to talk about what he read he didn't know how it was pronounced... because he honestly didn't know.

Quoted from benheck:

My guess:
1) Someone DID try and "cancel" him by contacting his business.
2) They laughed it off. (businesses only care if you're sexist or racist)
3) Chris made the story up (if HR did have an issue I doubt he could speak of it publically)
4) He will have a GOTCHA episode and reveal who it was that tried to cancel him.
5) His intended backlash against that company or individual will be muted by the backlash against his hoax.
