Internal controversy at Facebook is escalating as employees express disappointment in Mark Zuckerberg's leadership. The backlash centers around Zuckerberg's decision not to remove posts that some Facebook employees believe could incite violence. Natasha Lamb, managing director at Arjuna Capital, joins "Squawk Box" to discuss. Facebook CEO Mark Zuckerberg on Tuesday told employees that he was standing firm in the company’s decision not to moderate a post in which President Donald Trump said “when the looting starts, the shooting starts.” Zuckerberg announced this to employees during a virtual all-hands meeting on Tuesday, according to The New York Times. The decision comes despite public criticism from dozens of employees, many of whom argue that the post from Trump violates Facebook’s community standards, which prohibit language that incites serious violence. Brandon Dail, a Facebook user interface engineer, tweeted on Tuesday in criticism of Facebook’s leaders. Zuckerberg’s decision not to moderate the post is in contrast to that of rival Twitter, which placed a label warning users about the president’s violent rhetoric, which they have to dismiss before they can view the tweet. Twitter is also preventing users from liking or retweeting the tweet. Aside from criticism of the decision, at least two Facebook employees posted on social media that they were leaving the company as a result of the refusal to moderate Trump. “I cannot stand by Facebook’s continued refusal to act on the president’s bigoted messages aimed at radicalizing the American public,” software engineer Timothy Aveni posted on LinkedIn. Others in the tech industry also criticized the company for its inaction. Data scientist Ayodele Odubela on Tuesday tweeted a screenshot of her response to a Facebook recruiter, saying she refused to work for a company with policies that she fundamentally disagrees with.
