FWIW, since they updated the google news algorithm, I've started getting a pretty diverse set of results. It might be because it picked up that I try to read opposing views, or it might be because the algorithm is terrible, or any other number of reasons, but regardless of the source it's refreshing to see.
...and revealing! The headlines differences between, say, Washington Post, CNN, The Hill, and Fox News for the same news blurb is even more dramatic than I'd expect when you put them up side-by-side.
None of which contradicts your point, I just wanted to flag a happy instance where the result wasn't just "yo dawg".
