Facebook is known for its goal to cover every single inch of the planet with its services and China is known for blocking companies that don’t comply with its censorship regulations. In an effort to appease the Chinese government and enter one of the largest markets in the world, Facebook decided to build a tool that would censor content.

Facebook’s founder Mark Zuckerberg has been hard at work in getting on the good side of Chinese leaders and moguls over the past few years and has visited the country multiple times to that end, The New York Times reports. It would seem that in order to cultivate close relationships with the country, the social media site has had to make certain compromises, including the creation of software that could suppress certain content from appearing on news feeds.

The information comes from three sources within Facebook, who opted to remain anonymous due to the level of secrecy placed on the project. It would seem that the tool targets geo-specific users in order to prevent content that the Chinese government deems inappropriate from appearing.

In light of this information, Zuckerberg could be facing a substantial wave of criticism, which is only made worse by his statements over the last few days that Facebook could not do anything about the spread of fake news, nor could he be the arbiter of truth. The sources indicated that Zuckerberg placed his full support behind the development and deployment of the tool, even defending its existence to those who objected to it.

However, it appears that Facebook is only developing the gun that will suppress information for Chinese users, Business Insider notes. Others will be pulling the trigger, which will likely be third-party companies under the employ of the Chinese government.

There’s also no guarantee that Facebook would even go ahead with releasing the tool to authorities in China in the first place. It’s just as likely to be boxed away as another idea that didn’t work out.
