Suppose you host your podcast on a platform like Libsyn or Podbean. What happens if you decide to switch podcast platforms? You already gave everyone a RSS URL that pointed to your old platform. For example Libsyn gives your podcast an RSS URL like this: https://feeds.libsyn.com/12345/rss When you submitted your podcast to Apple Podcasts and shared your RSS URL with your listeners, you pointed them directly to your podcast platform.
