> In what way does the ecosystem rely on Apple's infrastructure? Do listeners on Android, or even a third-party apps on iOS, use Apple's podcasts directory for search and discoverability? Depends on which client you use. Google Podcasts has its own directory. However, it's approximately-true that any third party app on iOS / Android that aren't run by a big company (Spotify, Google, Amazon) use Apple's directory for their podcast-search. (Pocket Casts, Castbox, etc on Android all definitely use it.)
