No need to install: Microsoft has controversial fake news filter NewsGuard built into mobile browser
Rather than having to download an app as before, Edge users on Android and Apple devices can now just click one button to enable its “green-red rating signal if a website is trying to get it right or instead has a hidden agenda or knowingly publishes falsehoods or propaganda.”
Among the green-rated websites: Voice of America, CNN, Buzzfeed, the Guardian, New York Times and the Washington Post, as well as left-leaning upstarts such as Vice News and Refinery 29. Ones that are given the red warning label of “failing to maintain basic standards of accuracy and accountability”: RT and Sputnik (obviously enough) and the right-wing Daily Mail, Breitbart and the Drudge Report, in addition to hundreds of other non-mainstream news websites such as Wikileaks.
