Facebook employees are staging a rebellion over Mark Zuckerberg’s refusal to act against Donald Trump, expressing their dissatisfaction with their boss on social media in a rare display of dissent from within the company.

Axar.az reports citing foreign media that disagreement came from employees at all levels of the company, including some senior staff. Particular criticism was levelled at Zuckerberg’s personal decision to leave up the Facebook version of a tweet sent by Trump in which the president appeared to encourage police to shoot rioters. By contrast, Twitter hid the message behind a warning.

Andrew Crow, the head of design for Facebook’s Portal video-phone, tweeted: “Giving a platform to incite violence and spread disinformation is unacceptable, regardless who you are or if it’s newsworthy. I disagree with Mark’s position and will work to make change happen.”
