"My guess is that all these advertisers will be back on the platform soon enough" the Facebook chief executive has said. Campaigners accuse the tech firm of being too slow and reluctant to remove some hateful content. But Zuckerberg added: "We're not going to change our policies or approach on anything because of a threat to a small percent of our revenue." The comments were made to Facebook staff at a private meeting last Friday, and were subsequently leaked to the Information news site. The social network has confirmed they are accurate and also announced a fresh development: its chief executive is to meet the organisers of the boycott - Stop Hate for Profit... This week Facebook sent an email to companies and ad agencies assuring them it was doing all it could to remove hate speech. "This work is never finished, and we're proud of how our apps can help people come together, learn, and organize against hate and show their solidarity" an email to one ad agency said.
