you may be correct about the last 3 but don't fool yourself about at least the first two. If they think it will get them clicks....
I get what you are saying but you can't point to low ethics from a position of "the other side" here. All of our biggest news media sources are worthless these days. And both political parties have just as much blame in it. If you are still buying in to either of these parties then you are also more likely to click articles that give you comfortable food for your confirmation bias. The partisan networks will gladly oblige.
