A former CEO of Facebook Australia and New Zealand has accused the social media giant of “bullying and intimidation” amid growing calls for a boycott following its decision to ban the sharing of news on its platform in Australia.

The site is also blocking Australian publishers from being seen by all Facebook users regardless of their location.

Stephen Scheeler said: “I’m a proud ex-Facebooker, but over the years I get more and more exasperated. For Facebook and Mark it’s too much about the money, and the power, and not about the good.” In particular, he was worried that banning established news outlets would make the spread of fake news on the site even worse.
