A “raw” RSS feeder will fetch the RSS entries and display them for you.
I presume paid features are meta around the RSS feeds.
So you could add your own notes to the items.
You could have groups/categories of items beyond just grouping by their source.
The service might fetch/cache them automatically, whereas a free one might not have an “always on” type functionality and might miss posts if it’s not pulling ever month or whatever (same, with errors).
On top of that, if another user on the service is subscribed to an RSS feed, you might be able to access the feeds history (beyond the timescale/history the feed keeps published).
The service might be able to highlight and alert you to updated posts, showing the difference between the revisions.
The service might also be able to recommend similar RSS feeds based on other users interests, aiding in discovery.
And all of this would by automatically synchronised between devices.
