We must face the fact that Facebook doesn’t care about news in the journalism sense. News represents about 10% of the average user newsfeed and news can be cut overnight if circumstances dictate with no significant impact for the platform.
On Facebook, what you click on, what you share with your “friends” shapes your profile, preferences, affinities, political opinions and your vision of the world. The last thing Facebook wants is to contradict you in any way. The sanction would be immediate: you’d click/share much less; even worse, you might cut your session short.
