Will OpenAI send police to your door if you advocate for AI regulation? Nathan Calvin, a lawyer who shapes policies surrounding the technology at Encode AI, claims OpenAI did just that.

“One Tuesday night, as my wife and I sat down for dinner, a sheriff’s deputy knocked on the door to serve me a subpoena from OpenAI,” Calvin writes on X. In addition to subpoenaing the organization he works for, Calvin claims that OpenAI subpoenaed him personally, with the sheriff’s deputy asking for his private messages with California legislators, college students, and former OpenAI employees.
