OpenAI Foundation — board-seats-controlled: All PBC board seats (sole appointment and removal authority)

Note: The source text directly confirms the claim. It explicitly states that the OpenAI Foundation has sole special voting and governance rights that allow it to appoint all PBC (OpenAI Group PBC) board members and can replace directors at any time. The claim's date specification (2025-10) aligns with the source's announcement date of October 28, 2025. The additional context about sole power and authority to appoint and remove is precisely what the source states.
