Facebook fired an employee who publicly criticized a coworker on Twitter for not adding a statement of support for Black Lives Matter to documentation on an open-source project they were working on.

Brandon Dail, a user interface engineer in Seattle, Washington, announced on Friday in a tweet that he was let go for calling out a colleague on Twitter.
