Fake news is cheap to produce. Genuine journalism is expensive.
The fake news is - I mean, as a tool of warfare - has been there for decades and decades and decades. It was never very well done until, really, the Ukraine, though I would say that the Russians used to complain about fake things to say the State Department.
In Germany, a country that for obvious reasons is far more attuned than most to the dangers of demagogy, populism, and nationalism, lawmakers have already proposed taking legal measures against fake news. When populist, nationalist fake news threatens the liberal democratic center, other Europeans may follow suit.
Because of cyberattacks and fake news, we can already imagine the problem all democratic societies will face in future elections: how to limit lies when they threaten democracy?
In Russia, tweeting or sharing real news that's embarrassing to the regime can land you in prison. Imagine, then, the response of the regime to 'fake news' that's damaging to the Kremlin.
