Behind the Bastards did an episode on him. Honestly I think from what I recall he was just drawing what got good feedback, but then he had a few issues with health, one that made him unable to speak for years and iirc ended his marriage?

So one of their takes is maybe this trauma did some damage to him mentally as well. I’m grossly oversimplfying, so I recommend checking the episode. You can also find statements and articles about his Spasmodic Aphonia and him attributing his divorce partially to it.

They do have some arguments against his anti-corporate rep though.
