> Searching “free speech” and getting an article about limits of free speech around the world would be perfectly reasonable.

Such a result would definitely be odd framing, though. Especially if it was the main infobox and not, say, the seventh result.

For instance, I could see a "soft authoritarian" regime subtly justifying its censorship regime by preferentially surfacing content that makes censorship seem more justified. One way to do that is to encourage the idea that "limits are common" and discourage the idea that "free speech is a natural right," which you can do by changing the search ranking to surface an article like you described.
