Following a long period of negative media coverage this year, the Wall Street Journal reports that Mark Zuckerberg told top employees that Facebook is "at war," and that he plans "to lead the company accordingly." But this internal shift seems to be creating some friction within the company. An unnamed source told the WSJ that the new approach is "driving several key executives from the company" and creating tension with Facebook's COO. Meanwhile, NBC claims that Both Zuckerberg and Sandberg blame the company's communication team and the press for a number of mistakes. In a meeting on Friday, Zuckeberg called a particularly scathing New York Times report "bulls---," and said he "would not hesitate to fire employees who leaked information to the media." Internally, the leadership's decision to blame the media and the press shop has driven a wedge between them and members of the communications team who feel as if they've been thrown under the bus, the sources said. "It's total arrogance," one Facebook employee said. "Everyone is pissed."
