OpenAI allegedly sent police to an AI regulation advocate’s door

Here is a 183-word summary of the news article: OpenAI, the prominent AI research company, allegedly sent a sheriff's deputy to the home of Nathan Calvin, a lawyer who advocates for AI regulation. Calvin claims OpenAI subpoenaed him and his organization, Encode AI, as part of a lawsuit against Elon Musk. According to Calvin, OpenAI subpoenaed his private messages with California legislators, college students, and former OpenAI employees, suggesting an attempt to intimidate critics of the company. Encode AI has been vocal about pressing OpenAI on preserving its nonprofit mission amidst corporate restructuring, and has supported Musk's efforts to block OpenAI from becoming for-profit. OpenAI stated that its goal was to understand Encode's involvement in Musk's legal challenge, and that it's common for deputies to serve as process servers. However, an OpenAI employee acknowledged that the company's actions "don't seem great" and that it has a duty to act as a "virtuous" power. Another AI watchdog group, The Midas Project, also reported receiving subpoenas from OpenAI seeking information about its contacts.
