Mark Zuckerberg is facing a reaction from his employees for what they say is inaction against inflammatory comments on the social networking site.
On Friday, U.S. President Donald Trump posted the same message on Zuckerberg's Twitter and Facebook, saying "when the looting begins, the shooting begins".
His posts responded to protests in the United States after the death of George Floyd, an unarmed black man who died after a white policeman knelt on his neck for more than eight minutes.
Donald Trump's tweet drove Twitter action, but not Facebook
Twitter posted a warning in the tweet saying it had violated the site's rules against glorifying violence, but that it was being left as a public service exception.
Facebook took no action against posting on its website.
Reuters news agency reported at least seven social media posts from Facebook employees criticizing the lack of action against the post, three of which were identified as senior managers.

Ryan Freitas, whose Twitter account identifies him as director of product design for Facebook's News Feed, said, "Mark is wrong, and I will try my best to change my mind."
He added that he mobilized more than 50 "like-minded people" to push for changes in the technology company.
Jason Toff, identified as director of product management, wrote: "I work on Facebook and I'm not proud of how we're showing up. Most of the coworkers I spoke with feel the same way. We're making our voice heard."
David Gillis, identified as director of product design, praised Twitter's response, saying, "I think it would be right for us to create an exception to the" spirit of politics "that would take the context more into account."
Andrew Crow, head of product design for Portal, said: "It is unacceptable to provide a platform to incite violence and spread disinformation, regardless of who you are or whether you are noteworthy.

"I disagree with Mark's position and will work to make the change happen."
Facebook did not comment, but on Friday Zuckerberg tried to explain the lack of action, saying that while he finds the remarks "deeply offensive", they do not violate Facebook's policies.
He also said that people should know if the government was planning to send force and that his company had explained its policies to the White House.
