Newsguard is funded by mainstream media, you will find when using this addon that it has very strong left-leaning bias. It is a nice idea of an addon but unfortunately the desires and bias of the people who run it dictate what is marked as acceptable or not. You're better off deciding which news to read for yourself, newsguard is NOT non-partisan.
Helps with determining the quality of journalism of many sites. It's very useful for showing older or less informed readers the quality and objectivity of what they're looking at, and giving a good idea of the quality of the reporting at a glance.
Hopefully this will help inspire more transparent news reporting in the future!
Huffington Post gets an all clear rating? Did you even read your analysis? You say they have an opinion section but sometimes opinions slip through. Search for Trump Racist in any search engine and they have an article from a few years ago "Here Are 13 Examples Of Donald Trump Being Racist." In the Politics section - not Opinion - sources about 20 other news sites (unoriginal much), and ends with an endorsement by the editorial staff:
"Editor’s note: Donald Trump is a serial liar, rampant xenophobe, racist, misogynist, birther and bully who has repeatedly pledged to ban all Muslims ― 1.6 billion members of an entire religion ― from entering the U.S."
As objective as I can be, that doesn't sound like journalism. It sounds like a freelance, rookie staffer sat down, skimmed the headlines, and wrote a frenzied article. I could've hired a kid in high school to write something with more value.
