One day in late February of 2016, Mark Zuckerberg sent a memo to all of Facebook’s employees to address some troubling behavior in the ranks. His message pertained to some walls at the company’s Menlo Park headquarters where staffers are encouraged to scribble notes and signatures. On at least a couple of occasions, someone had crossed out the words “Black Lives Matter” and replaced them with “All Lives Matter.” Zuckerberg wanted whoever was responsible to cut it out.
“ ‘Black Lives Matter’ doesn’t mean other lives don’t,” he wrote. “We’ve never had rules around what people can write on our walls,” the memo went on. But “crossing out something means silencing speech, or that one person’s speech is more important than another’s.” The defacement, he said, was being investigated.
All around the country at about this time, debates about race and politics were becoming increasingly raw. Donald Trump had just won the South Carolina primary, lashed out at the Pope over immigration, and earned the enthusiastic support of David Duke. Hillary Clinton had just defeated Bernie Sanders in Nevada, only to have an activist from Black Lives Matter interrupt a speech of hers to protest racially charged statements she’d made two decades before. And on Facebook, a popular group called Blacktivist was gaining traction by blasting out messages like “American economy and power were built on forced migration and torture.”
So when Zuckerberg’s admonition circulated, a young contract employee named Benjamin Fearnow decided it might be newsworthy. He took a screenshot on his personal laptop and sent the image to a friend named Michael Nuñez, who worked at the tech-news site Gizmodo. Nuñez promptly published a brief story about Zuckerberg’s memo.
