OpenAI Foundation — key-event: OpenAI announces plan to restructure into PBC; initial plan would have removed nonprofit governance control

NoteThe source directly confirms the claim's core elements: (1) OpenAI announced a plan to restructure into a PBC (confirmed: 'transform our existing for-profit into a Delaware Public Benefit Corporation'); (2) the announcement occurred in December 2024 (confirmed: dated December 27, 2024); (3) the initial plan would have removed nonprofit governance control over operations (confirmed: the PBC 'will run and control OpenAI's operations and business' while the nonprofit pursues separate charitable initiatives, representing a shift from the current structure where 'the for-profit [is] controlled by the non-profit'). The source frames this as 'evolving' the mission to support it better, which aligns with the claim's note that 'OpenAI framed this as evolving the mission.' The source does not explicitly address critics' perspectives, but that contextual framing does not contradict the factual announcement itself.
