Does the new podcast mac app allow you to see the RSS feed like iTunes? If so, I wonder if you could extract the exclusive podcasts' feed URL and use it in 3rd party apps.
I can't answer your question, but as someone who uses ruby scripts to do custom filtering on podcast feeds, I can say that iTunes is one of the biggest PITAs to work with. Constantly evolving to further obscure the inner workings. Apple isn't the only one, but they are definitely the 10,000 lb gorilla.
I was more referring to the feature where if you already subscribe to a feed, you can get the URL from either the right-click menu or menu bar menu. Although I remember there being a way to get the RSS feed from the Apple Podcast webpage for the podcast; is this what you are talking about?
Sorry I missed your reply earlier. I was more referring to getting at the RSS feed URL from an iTunes link
If they’re exclusive to Apple, there isn’t much of a reason to have a RSS feed.
If they stick with RSS, they won't have to write/test a new feed format and parser. RSS (and the podcast extensions to it) are pretty battle-tested at this point.
