Fake news can't be solved with bans, only through education. Education is a long term investment though and everyone wants immediate fixes. Expect more of this nonsensical short term thinking.
I think the issue is people latch on to these things due to feeling or being powerless. They reach for solutions rather than being stuck in an endless waiting or trusting period, hoping for remote experts to do something. Education can help that but not always, and especially if the experts are adversarial to groups of people.
I've been brought up with the saying, 'The sole purpose of education is to help a person think sensibly in difficult times'.
However, I've not come across any _major_ shift in education systems worldwide. Yes, there are heartening stories about a few charter school systems [1] and a few countries making strides (like Finland). But these are one off success stories.
I do hope that technology companies make a step towards solving this. But our startup culture, unfortunately, also is laced with trying to 'show growth' all the time and that leads us to think short term too. Perhaps something like the LTSE may help private players take long term bets (fingers crossed).
Also, even the history of education is ripe with missteps [2], mind you :) not unlike the decision by YouTube here (as someone said, The road to hell is paved with good intentions)
Don't get me wrong, I want to be as optimistic as you are :)
