"Amid this global movement to end anti-Blackness, we credit these companies for answering our call swiftly and taking a clear stand for what's right so we can hold Facebook accountable for its racist policies," said Rashad Robinson, president of Color of Change, which is one of the groups organizing the boycott.
Almost 100 firms have joined the boycott so far, Robinson said, adding: "Facebook has a decision to make: adopt a civil rights infrastructure or continue to see key advertisers dropping from its platform."
Most recently, the tension between Facebook and the content its users share has come to a head due to messages posted by President Donald Trump and his re-election campaign in the past month, amid nationwide protests in support of Black communities and against police violence. Twitter in late May took action against a Trump tweet by appending a warning that it glorified violence against protesters, in contravention of the site's rules. Facebook, however, took no action against the same content, and the company took heat from both civil rights advocates and employees over that choice.
