Decentralizing won't help much.

The who really knows what is fake news? And what about the filter bubbles that keep the full picture hidden from you?

A decentralized search engine with configurable or even just inspectable filter bubble would be a good start?

(Although I think the correct abstraction is not "search engine", but "decentralized content index" + "decentralized content ranking" with tweakable parameters.)
