OpenAI Refuses Central Control, Empowers Verified Defenders

#OpenAI shots fired “We don’t think it’s practical or appropriate to centrally decide who gets to defend themselves. Instead, we aim to enable as many legitimate defenders as possible, with access grounded in verification, trust signals, & accountability.” https://t.co/KM1Vr7Idej
