The news is particularly rough for Facebook, especially in the case of Chris Cox, who was considered for many as the number 3 company, behind Mark Zuckerberg and Sheryl Sandberg. The man, 36-year-old has been one of the first engineers recruited by the social network. He has been responsible for the development of several products that have made the success of the platform, in particular the news feed. He has also held the position of director of human resources, taking care of the recruitment of the employees of Facebook. Since last year, Chris Cox had more particularly the responsibility to develop the ecosystem of applications from the social network.

"Chris and I have worked together to build our products for more than ten years, and I will always be grateful for her empathy vis-à-vis our users and the joy that he brings into everything he does," said Mark Zuckerberg, in a news release announcing the new. "The transition, Chris has also recruited and trained many of the leaders who now occupy important roles in our company - including the people who are going to have, now, with more responsibilities in the development of our future products." The CEO of Facebook says that Chris Cox had expressed the desire to "do something else" than work within the social network from 2016.

However, the New York Times , which cites six sources close to the matter, the departure of Chris Cox would be especially due to a disagreement with some decisions of Mark Zuckerberg. At the beginning of march, the CEO has unveiled an ambitious plan to overhaul the various applications of Facebook, linking to the infrastructure of Instagram, Messenger and WhatsApp, in order to facilitate the communications between these services, but also the intersection of data and their exploitation for the benefit of Facebook. He intends to make the social network a platform that focuses more on the private conversations than before. In a post published on its own page Facebook, Chris Cox has more or less confirmed this theory. "As Mark said, a new page turns for our products. It is a huge project, and Facebook is going to need leaders who are excited about this new direction," wrote the engineer. Chris Cox will be replaced by the French Fidji Simo, up here in charge of the tools of video within the social network.

on Thursday, Mark Zuckerberg has also announced the departure of Chris Daniels, who was in charge of the messaging WhatsApp. This service, which was acquired in 2014 by Facebook, has undergone many transformations in recent years. Its two co-founders, Brian Acton and Jan Koum, both have taken the door in 2018, unhappy with the direction taken by the application. Mark Zuckerberg wants to make WhatsApp as the cornerstone of the future of Facebook, by exploiting further the data of its users and placing ads. Chris Daniel will be replaced by Will Cathcart, who was so far in the team dedicated to the products of Facebook.

This british company is accused of stealing data from users Facebook for the benefit of political campaigns in favor of Donald Trump and the Brexit. However, these whirlpool internal also comes from the own-making of Mark Zuckerberg, who seems determined to change the culture of Facebook with more promotion of the private communication rather than public discussion. "This decision is necessarily controversial," said Ben Horowitz, an investor in the famous fund california Andreessen Horowitz, on Twitter. "Facebook is known (and always for good reasons) for his social network public. It is a real earthquake cultural."
