The two sides tore each other apart, attacking each other, accusing each other.
On the evening of November 3, 2010, at 6:00 PM, Penguin released an open letter claiming that its chat software would stop functioning on computers with 360 software installed, demanding the uninstallation of 360 before logging into their chat software. This was Penguin's most dramatic action in a series of disputes with 360, leaving many netizens caught in the crossfire.
This move caused a stir in the industry, and netizens were outraged. Industry insiders felt that Penguin's tactic was forcing users to make a choice between the two.
According to 360 CEO Zhou Hongyi, the number of 360 software users forced to uninstall reached 60 million.
Due to the widespread concern caused by the incident, on the morning of November 5, the Ministry of Industry and Information Technology and the Internet Association held a meeting to discuss measures in response to this issue.
