Yeah it’s not the cartoonist. It’s the media corporation they operate through.
It’s not a secret that media outlets heavily influence what is aired on their channels. Hell they determine what they air in the first place. That and the FCC is a govt agency that determines what is or is not appropriate for public television. And with half our govt trying to strip education it’s not that far of a stretch.
The actual cartoonist is usually on the lower end of the power dynamic. You make what they tell you to make or you don’t work for them.
