There are readers with a 'full text mode' which will fetch the website and display it in something like Mozilla's Readability view. It does not always work, especially if the page is paywalled but it works for most sites.
If you're paying, there's probably a way to get a RSS feed for paid subscribers. If you can't find it, maybe email tech support?
This is how all the podcasts I donate to work (they offer ad-free feeds, bonus episodes, etc, usually with some url like https://rss.podcastsite.com/show?token=<random code>, and then in my podcast app, it either says "Some show - Paid feed", or sometimes "Some show - your name's feed".
