Then you have this at the very end:

OpenAI was founded as a non-profit in 2015 with the core mission of ensuring that artificial general intelligence benefits all of humanity. In 2019, OpenAI restructured to ensure that the company could raise capital in pursuit of this mission, while preserving the nonprofit's mission, governance, and oversight. The majority of the board is independent, and the independent directors do not hold equity in OpenAI. While the company has experienced dramatic growth, it remains the fundamental governance responsibility of the board to advance OpenAI’s mission and preserve the principles of its Charter.

Then you have this in Greg's resignation on Twitter:

i continue to believe in the mission of creating safe AGI that benefits all of humanity.

My money is on this being related to the way OpenAI suddenly became 'ClosedAI' with GPT-4 under the chain of it being about safety which ended up very profitable for them but has hampered global research and advancement on LLMs. Especially as they are now working on GPT-5.

The "not consistently candid" may have been him claiming such closed measures were temporary or limited but then continued to double down on them.

But it's pretty clear the board sees the responsibilities he was interfering with as their core mission given the way they ended the announcement.

I tbk m much more likes disagreement about commercialisation

Well they wouldn't want their face to be accused of sexual assault. It would look bad.
