Wikipedia cofounder Larry Sanger blocked from editing Wikipedia

Wikipedia cofounder Larry Sanger has been banned from editing the platform but returned in fall 2025 to advocate for reforms through a new WikiProject Intellectual Diversity. Sanger has developed "Nine Theses on Wikipedia," a reform proposal that criticizes current Wikipedia policies and calls for changes including ending consensus-based decision-making, abolishing source blacklists, enabling competing articles, and implementing a legislative process. He is actively seeking support to reshape Wikipedia into a more open and intellectually diverse platform.
