What is Facebook without news? People and publishers in Australia are now finding out. Facebook (FB) has barred Australians from finding or sharing news on its service, a dramatic escalation of a fight with the government that may have wide-ranging consequences both in the country and around the world. The social networking company on Wednesday said that people and publishers in Australia will no longer be able to share or see any news from local or international outlets. The decision appears to be the most restrictive move Facebook has ever taken against content publishers. The company’s action comes after months of tension with the Australian government, which has proposed legislation that would force tech platforms to pay news publishers for content.
