The so-called Internet freedom is a new weapon used by the United States to interfere in the internal affairs of other countries. After US Secretary of State Hillary Clinton took office, she delivered two speeches advocating an open Internet. It can be seen that the Internet has become a diplomatic tool and a tool to promote the American model. Hillary Clinton also repeatedly accused the Chinese government of restricting the "free flow of information" on the Internet. Sergey Brin, one of the founders of Google in the United States, said that China is the enemy of Internet freedom.
