Fediverse

Fair. Though that capability - e.g. the identical wikia software, implementing the MediaWiki protocol - already exists. Maybe federating it would somehow improve it, though it would also open it up to have greater vulnerabilities especially when non-scientists get involved, e.g. a w/article/conservative/vaccine vs. a w/article/real/vaccine. Scientists can handle these controversies, but people who do not have the base knowledge with which to properly understand, e.g. ivermectin, are not going to be able to distinguish between the truth vs. the lies.

So the people that would put it to the best use don't absolutely need it - sure it would be nice but peer-reviewed articles already exist - while the ones for whom it would be most damaging are almost certainly going to be the primary target audience.
