Brazil’s biggest newspaper, the Folha de S Paulo, has announced that it will no longer publish content on its Facebook page, accusing the social media giant of encouraging fake news with an overhaul of its news feed algorithm.

Mark Zuckerberg, Facebook’s co-founder and CEO, has said the algorithm change announced last month will prioritize “meaningful social interactions” and personal posts instead of content from businesses, brands and media.
