They love to write about scandals and problems. But if you have an actual solution to the problem, they aren’t going to publish it.
You can also see articles on court cases about some scandalous things, but can hardly find out how the case eventually turned out. And so on.
Journalism highlights problems not solutions because that’s what gets the most “outrage reshares”. The exception is some “cool new technology” that can have a story about it, but not as a SOLUTION associated to a lot of PROBLEM stories.
They particularly love to write about scandals and problems among their rivals. That's the real change here: journalists and bloggers have gone from thinking of Facebook (and other social media) as potential allies to thinking of them as rivals. Negativity sells, as you say, but negativity that reinforces one's view of rivals as evil is especially appealing. People whose own Google Ads revenue is declining because the eyeballs are elsewhere are very highly motivated, both consciously and unconsciously, to write about why those eyeballs are elsewhere when they clearly shouldn't be.
Currently, because of facebook, there is a spike of Company Y knows everything about you type stories, as well as a spike of Facebook is evil stories. These things permeate out and loose interest over time.
