In an unprecedented move, Facebook is restricting users in Australia from sharing or viewing news on the social network. Facebook is also stopping users from outside of Australia from viewing or sharing Australian content from Australian news Pages.

The move highlights the immense power that social networks have over peoples' sharing and consumption of news, and their ability to take that away. Facebook's actions come in response to Australia's proposed Media Bargaining law, which would require internet platforms to pay news organizations for their content; Google has also threatened to pull out of the country to avoid paying news organizations.
