1. The company has built a culture around not being under control by one single company, Microsoft in this case. Employees may overwhelmingly agree.
2. The board acted rashly in the first place, and over 2/3 of employees signed their intent to quit if the board hadn't been replaced.
3. Younger folks probably don't look highly at boards in general, because they never get to interact with them. They also sometimes dictate product outcomes that could go against the creative freedoms and autonomy employees are looking for. Boards are also focused on profits, which is a net-good for the company, but threatens the culture of "for the good of humanity" that hooks people.
4. The high success of OpenAI has probably inspired loyalty in its employees, so long as it remains stable, and their perception of what stability is means that the company ultimately changes little. Being "acquired" by Microsoft here may mean major shakeups and potential layoffs. There's no guarantees for the bulk of workers here.
I'm reading into the variables and using intuition to make these guesses, but all to suggest: it's complicated, and sometimes outliers like these can happen if those variables create enough alignment, if they seem common-sensical enough to most.
Judging from the photos I've seen of the principals in this story, none of them looks to be over 30, and some of them look like schoolkids. I'm referring to the board members.
It's a common theme in the overall critique of late stage capitalism, is all I'm saying — and that it could be a factor in influencing OpenAI's employees' decisions to seek action that specifically eliminates the current board, as a matter of inherent bias that boards act problematically to begin with.
