I listened to much of the interview on the radio. He touched on a lot of good points and then came to the absolutely wrong conclusion. He talked about how many writing rooms are "writing by committee" where jokes will go through a review by many different groups. If this is truly the case (I don't know) that is not an issue if the "far left mob" but rather the enshitification of comedy due to corporations and Wall Street bankrolling these productions wanting to ensure return on investment. This kills creativity by reducing risks. Topical comedy is a risky medium by default.
Also, shout out to Rob McElhenney for his sarcastic one word response. In Jerry's imagined world, It's Always Sunny in Philadelphia can't exist.
