To put these claims in a published paper in such a naive way with no disclosure is academically disingenuous.
Academically, did she not disclose being on the board on her paper?
Being at the top of the org and being present during the specific incidents that gives one qualms burdens one with moral responsibility, even if they were the one who voted against.
You shouldn’t say “they did [x]” instead of “we did [x]” when x is bad and you were part of the team.
Or, that she should write her paper in the first person: "We, OpenAI, are doing bad things." That would probably be seen as vastly more damaging to OpenAI, and also ridiculous since she doesn't have the right to represent OpenAI as "we".
I have no idea why you think that should be a rule, aside from wanting Helen to never be able to criticize OpenAI publicly. I think it's good for the public if a board member will report what they see as potentially harmful internal problems.
Regarding specific verbiage and grammar, I’m sure an academic could give clearer guidance on what is better form in professional writing. What was presented was clearly lacking.
