Well, yes and no. Does the media sometimes present propaganda and fake news as fact? Sure. Not always, but sure, it happens. Calling out specific media outlets when they do this is absolutely necessary. Of course, labeling media as fake news simply because the facts they report disagree with your ideology is dishonest and reprehensible.
Also syndication is probably not as important online when you could just link to the article source.
Also negative "news" sells better. Humans just respond to fear and hatred. It is just so much easier to fear and to hate. I'll admit to it. I feel suspicious when I see something positive in the news: is this a sponsored post?
