Do you know _why_ this uptick has happened? Does anyone?
I get the feeling, in general, when people talk about wanting to "Do Something" about this sort of thing, they are always focused on managing the symptom and never focused on addressing the cause. Frequently, when I try to bring this up, the cause is waved away with "oh they're just stupid/ignorant/angry" or some other such explanation. The current-year favourite is "they just believe fake news", and I'm sure next year there will be a political explanation, and then the year after that we'll loop back to generic ones. (The irony of denouncing other people as causing polarization "because they're just angry and stupid" is lost on most people)
I don't know why this is happening. But I do know that until the why is address, and done so with care and respect, this problem will be papered over at best but never solved.

> Do we ditch them and go back to a literal timeline?
If I got one wish to change the world, but I had to give up a bunch of great things, I would sell out all technological wonder in order to get literal timelines back. As soon as other people decided they knew what I wanted to see better than I did, the problem started. And as soon as they got tired of doing that and made computers do it for them, it got worse
