Circa News from 2012 (now closed) had some similarities to what you are describing.

Basically they would distill an article down to facts with links to the original source of the facts. Users could subscribe to a story and it would update you when a new substantive fact was added to the story.

I found Circa to be an amazing way to consume news. News was written in the most boring way possible, and it would have bullet points for news stories along with sources for each bullet point. As much as I like reading full articles to get all the nuance, there's just too much information to consume. Circa seemed to be the sweet spot between brevity and information density that I need.

I've been hoping for something like Circa to pop back into existence, but unfortunately I can see why it's not a profitable venture.
