Why are some people so against editing their podcast?

I've run across several podcasts out in the wild that are obviously not edited, and I've even seen some people on here who are hostile to the suggestion and insist on leaving their podcast unedited.

Most podcasts are edited, and the ones that aren’t usually have a professional host and guest along with a producer. Sure, there are exceptions to every rule, but in most cases, unedited conversation just doesn’t sound good.

If you can talk about your topic without too many mistakes and don’t need to edit than more power to you. But I think people underestimate how hard that is to do.
