This is a political fight. The mistake is believing in some sort of disinterested, unbiased institution adjudicating truth separate from influences of interest groups and political power.

The existence of power-centers like giant social media monopolies guarantees they are targets for political interests to hijack that power & censor opponents. Even if you could snap your fingers and magically populate these dominant platforms, and media/journalist institutions as well, with good faith actors (even here they are limited by their ability to actually know what is true), this wouldn't be a stable equilibrium and would in short order be populated and/or lobbied/pressured/swayed by political opportunists.
