I don't know this for certain but I strongly suspect news (and reviews/criticism, which is editorialised news) doesn't make up a huge percentage of search traffic. People read news sites that align with their preexisting points of view. They don't often go looking for new perspectives. If someone wants to know what's happening they want the filter of their preferred news outlet, if they want a review they want to read or watch their preferred reviewer. They don't want whatever happens to be the top search result.

Although, that said, with Google personalising search results the top result is very likely to be the user's preferred site anyway. We can't have people seeing outside their filter bubble after all.
