Let's be honest RSS wouldn't live anyway...
Like the only pages that would provide it would be the ones that don't have or have barely any ad and that's a minority that let's be honest doesn't stop them from providing it now.
The rest of pages would either not do it, do a very basic thing with only the title and small description so you have to click it to see the article or just find a way to add ads and tracking to it. Because they want/need you to watch ads, sell your data with tracking and all that.
