I think they just gave an example for how podcasts often feel to them. And I can relate, most podcasts feel like the podcaster assumes a certain norm and presenting topics as absolute truths. Someone here mentioned darknet diaries for example and I tried listening to this podcast but was deterred by his assumptions of how everyone wants to accumulate money and how he is obviously very oblivious of his political bias (i.e. trying to be apolitical but thus supporting a government’s military and political decisions). I guess this problem of thinking one is apolitical while actually talking about highly political stuff is more prevalent in cis male dominated spaces like tech (imo because of the combination of less empathy, a more self-centered viewpoint and a confidence in one’s own correctness). But as given per example by the other commenter, societal norms at large give people the feeling that they are correct in their views and that things just are a certain way (e.g. sex differences, certain experiences etc). Well, just wanted to give my mustard to it ;)
My problem is I don’t see how that relates to podcasts. It’s just a medium. Everything you describe can happen everywhere else.
Edit: Maybe what you’re missing are journalistic standards. Most podcasts are for entertainment and you might need to dig a little deeper to find professional journalism.
