It might not seem like the case right now, but I think the real disruption is just about to begin. OpenAI does not have in its DNA to win, they're too short-sighted and reactive. Big techs will have incredible distribution power but a real disruptor must be brewing somewhere unnoticed, for now.
That they reached a different conclusion than the outcome you wished for does not indicate a lack of critical thinking skills. They have a different set of information than you do, and reached a different conclusion.
Only time will tell if this was a good or bad outcome, but for now the damage is done and OpenAI has a lot of trust rebuilding to do to shake off the reputation that it now has after this circus.
When you see 95%+ consensus from 800 employees, that doesn't suggest tanks and police dogs intimidating people at the voting booth.
DEI and similar programs use very specific racial language to manipulate everyone into believing whiteness is evil and that rallying around that is the end goal for everyone in a company.
On a similar note, the company has already established certain missions and values that new hires may strongly align with like: "Discovering and enacting the path to safe artificial general intelligence", given not only the excitement around AI's possibilities but also the social responsibility of developing it safely. Both are highly appealing goals that are bound to change humanity forever and it would be monumentally exciting to play a part in that.
Thus, it's safe to think that most employees who are lucky to have earned a chance at participating would want to preserve that, if they're aligned.
This kind of alignment is not the bad thing people think it is. There's nothing quite like a well-oiled machine, even if the perception of diversity from the outside falls by the wayside.
Diversity is too often sought after for vanity, rather than practical purposes. This is the danger of coercive, box-checking ESG goals we're seeing plague companies, to the extent that it's becoming unpopular to chase after due to the strongly partisan political connotations it brings.
