Your mileage may vary, but I only ever wanted RSS feeds that provide the actual article content. Just spitting out a feed of links back to the site with headlines is not how I or many others used RSS and RSS readers wayback when. Full article feeds have all but died out now anyway, another nail in the RSS coffin for me.
That's my issue as well with the RSS feeds I use. None of them are full article feeds anymore. These sorts of RSS feeds are a way I can still centralize my feed data, even though they isn't true offline copies. I think this has to do with monetization and wanting to change the text of pages ad-hoc.
It's of course monetization. Everyone jumped on giving away their content via RSS/public APIs in the early rush to web2.0 style standards, then of course retreated from that position when it became clear directing eyeballs to the actual site and keeping those eyeballs there for as long as possible was required to maximize ad revenues, especially for sites giving away written content. The only full content feeds that really survive are the occasional blog or site that offers it as a bonus to paying subscribers.
No worries. I did this search on Google: https://www.google.com/search?q=axios+rss I've found this helps to find these sorts of feeds that don't easily show on the site's themselves.
