There is a more fundamental problem here. The news feeds are going in this direction for a reason. I don't think you addressed that reason.
You have defined the desirable news as "pure, essential information". What's that again? How do you know what's pure and essential info for any user? The traditional news media had started there, with that pure news, and ended up here where they are today.
Ultimately, you will realize that your content need to grab attention enough so that people consume your feed. People's attention goes to where things look weird, exciting, sensational, emotional, trivia, gossip etc. You can't do away with all that and just dish out the pure and essential info. It didn't work. People tried it.
