When the "creator" runs ads on their webpage they get paid per impression. With RSS they can't lock content behind a wall of JavaScript (and the associated AdTech). So they want to drive clicks to their ads.

This all means content creators are incentivized to make feeds that only link to their ad-laden web content. At best they'll put a tiny snippet of content in the post's description but the common case is just an empty description. End users of RSS want to have the actual content inside their reader. Reader apps often have features to detect link-only feeds and then go fetch the web content and display it in a Reader Mode fashion. This is at odds with the co tent creator wanting to show their ads.

This feeds (pun intended) into the question of repurposing. If a site has an easy way to find all the latest posts it becomes relatively easy for a third party grab that content and repost it. This was an explicit function of the old Planet software. It would aggregate a bunch of feeds together into a "river of news" format.
