Should say to start I'm not *against* white/straight/cis voices in a conversation so long as they're one of many perspectives being recognized
but one of the dudes from SYSK started a middle-aged-white-dude-yammering-about-films podcast, and of the six guests he lists in the ad, four are more middle aged white dudes, only one guest is queer and none are people of color. Just on a marketing level nothing about this makes me want to check out the show.
But I checked the archive, and out of the 20 episodes with guests he's never had on a single POC and only three women, so it's not just a failing on the advertising's part.
