The social media site Facebook blocked Australians from sharing news stories on Thursday. The company is fighting with the Australian government over whether big technology companies should have to pay news organizations for their information. Australia’s government condemned the move. It said Facebook also blocked some government communications, including messages about emergency services. Facebook acted after the Australian House of Representatives passed legislation that would make it and Google pay for Australian journalism, said Treasurer Josh Frydenberg. He said he was given no warning before Facebook acted. The legislation must be passed by the Senate to become law. Facebook fears that similar legislation will pass in other countries. Governments around the world are changing their laws to have some control over fast-changing technology.
