It has been a bad couple of weeks for Facebook. After years of fending off concerns about its poor privacy controls, the $500 billion social media giant was rocked last month by reports that it had allowed a UK data firm Cambridge Analytica to harvest personal details from 50 million Facebook users to feed to the Trump campaign in the 2016 US presidential election.
Whistleblower Christopher Wylie has since claimed similar information was used to influence the Brexit vote and elections in Kenya and Nigeria. A British parliamentary committee has called for Facebook chief executive Mark Zuckerberg to explain and the UK's information commissioner has launched her own investigation.
Facebook's share price has since plunged by 18 per cent and Zuckerberg, after days of silence, eventually made a public statement apologising and promising to limit the information given to apps in future.
It remains to be seen how much this difference this will make. As several journalists have illustrated, it is startling to discover how much detailed information Facebook already has for advertisers to target its users and all their friends.
Meanwhile in New Zealand privacy commissioner John Edwards has taken Facebook to task for refusing to comply with this country's privacy laws. The company initially argued that because its New Zealand service was provided by Facebook Ireland, it was therefore subject only to Irish law.
