I would imagine the parent comment is in regards to how people listen to podcasts. According to Anchor, Apple Podcasts boasts a 52% market share of how people listen to podcasts - https://medium.com/anchor/how-people-listen-to-podcasts-ba0c....

The power and reach of the default install of Apple Podcasts is hard to ignore. (which I don't believe most Android phones have).

ITunes and Apple Music are also available in Windows and in Android. You could argue about whether those versions are good or bad, but if you want to use them, you can. The discovery features works just fine, as long as you install the apps.

If podcasts are substantially more popular with Apple device users than they are in the broader population, it is entirely possible.

You think incorrectly :) I've never owned an Apple device in my life.

It's not a mathematical impossibility because, as far as I know, podcast listeners are still quite a small number. Plus, you forgot iPod owners (I know a few Android users who carry an iPod when exercising).

The real reason is because getting your podcast listed in the iTunes podcast directory takes care of making it available (via search, instead of copying and pasting an RSS feed url) in most podcast apps on most platforms.

iTunes is probably central to the ecosystem in the same way that the NEw York Times drives the national political conversation although only about two in 100 Americans actually read it: it’s an authoritative source and the people who do read/use it tend to be more influential.

I also wouldn’t underestimate the possibility that there is some correlation between enjoying the podcast format and Appple products. This American Life, as the prototypical podcast, is really what happens if you leave Jony Ive in a locked room with only a microphone and a dwindling supply of coffee.

The iTunes podcast directory is the defacto listing many (most?) podcast apps use. For many people if a podcast ends up only on Spotify, they will never even know it exists.

Iphone dominates the high end, and the high end dominates podcasts.

I run a site for us university students and it's roughly a 90%/10% split for ios/android.

Basically you're ignoring conditional probability.
