A Facebook algorithm wiped clean the pages of news publishers, government departments, emergency services and others as part of a campaign to put pressure on the Australian government, outraging local people and jeopardising their right to public information.  

The technology company blocked news journalism on its platform rather than pay the companies that produce it under the Australia's government's proposed News Media and Digital Platforms Mandatory Bargaining Code that would make platforms pay for publishers' content. 

However, the social network wiped clean the pages of new publishers, as well as of government departments, emergency services, non-profits and charities. Meantime, conspiracy theorist and anti-vaccine group pages were left untouched.

At the time, the move outraged Australians across all sections of society and raised questions about the accuracy of Facebook's content moderation and misinformation systems. Both systems had - and continue - to be widely accused of being ineffective, despite Facebook's insistence to the contrary.

The fracas also led some politicians and commentators to question whether Facebook had deliberately extended its news blocking activities to raise pressure on the Australian government - fears which appear to have been realised by a May 2022 Wall Street Journal report based on whistleblower testimony that indicated Facebook designed and used a custom algorithm for deciding what pages to take down that it knew would affect organisations other than news publishers, thereby ratcheting the pressure on the Australian government.

Facebook restored news to its platform after the Australian government introduced last-minute amendments to the legislation. 

An earlier threat by Google to shut down its search engine in Australia failed to materialise, with the search engine company instead choosing to forge private deals with news publishers.
