OpenAI Foundation — key-event: OpenAI reverses: nonprofit will retain governance control of PBC

Note: The source directly confirms all key elements of the claim: (1) the date is May 5, 2025 (matching 'as of 2025-05'), (2) the nonprofit retains governance control of the PBC, (3) this represents a reversal from an original plan (implied by 'updated plan' and the statement that they 'made the decision for the nonprofit to retain control'), and (4) the decision was made under pressure from CA AG, DE AG, and civic leaders. The source explicitly states these facts in the announcement and Sam's letter.
