According to PANews, Elon Musk stated that the best way to ensure the accuracy of the Community Notes system is for the system to be fully decentralized and open-source, including its code and data; any manipulation would be as obvious as 'neon lights'.
Musk added that platform staff, including himself, have no editorial control over the system. The system works by requiring agreement between historically opposing viewpoints in order for notes to be displayed on the platform.
