Google News is a dumpster fire. They include Sputnik and other govt propaganda sites from oppressive regimes.
Newsvoice was an app that tried to crowdsource that job instead of using algorithms. It very quickly became an alt-right cesspool, presumably because those are the same people who feel disenfranchised by FAKE NEWS LIBERAL MEDIA and so flock to alternative communities.
The utility of looking at multiple similar voices is to get a sense of the scale of a story, and inter-rater reliability; otherwise you have a portfolio of unweighted novelties.
