> Fake news is the symptom. The disease is confirmation bias.

When your root-cause analysis turns up an intractable problem that can't be solved, then maybe turn the intractable problem against itself.

Instead of eliminating filter bubbles and confirmation bias, encourage them. Herd the haters, trolls and propagandists into their own subgroups and shadow-ban them so people outside the group can't see them.

It doesn't solve the problem of confirmation bias, but it might help contain it and prevent wider contamination.
