I think Bill Burr, rightfully and the KSA thing notwithstanding, would push back on being a Bro-comedian. He, like Chappelle, seem to have a different point of view on popular ideas (e.g. WNBA/women's rights in that clip above, the BLM movement on SNL, trans and terf stuff with Chappelle) and they communicate that POV with humor. In some sense, at least when they were first speaking out on these, they were the counter-cultural POV and going against popularity.
Maybe what Marc is saying isn't wrong about some of those POVs and topics being old and hackneyed now-- but Burr and CHappelle and a few others are the tip of the spear. I think Marc is decrying the long tail, the rest of the wood behind the arrow, that have come along lately in the last few years and saturated the comedy circuit with those takes and he's talking about a whole horde of comediens we don't see or hear from second tier and down trying to make a name for themselves by getting in good graces with the "bro algorithms"?
