I can see the national security implications for countries like Russia and China, that are widely known for pushing false histories backed up with state punishment, but in high-functioning democracies the state does not control public speech.

what are the implications?

We've always been at war with Eurasia. Not all threats are external.

> national security implications (not just USA, but any democracy)

That's not really "national," is it?

National security doesn't just refer to USA...?

France has national security considerations, just like the UK, Uruguay and Uganda. They'd all benefit from having open access to verifiable information.

That's fine, it just seems more like a "societal security consideration," "democratic consideration," or just a general "consideration" than specifically "national security," which has the scope of a nation.

There are mirrors and backups of Wikipedia. Archive.org has no substitute.

archive.today at least allows people to preserve snapshots of selected websites, which is often important for being able to demonstrate that mainstream sources have edited or deleted content without proper acknowledgment.

Interestingly enough, Wikipedia once (I haven't checked if it's still in effect) blacklisted links to there, with compelling evidence (if you read any of the discussion behind the scenes) that it was actually about certain admins and power users trying to maintain control over the bias in main-space article content.
