Usually its something like president or chairman of the board, but that does not mean that person has unilateral decision making power. Even as head of the board he could be removed as CEO by the rest of the board, especially if the rest of the board thinks he needs to do more with AI. The point i am making is that by going public you give up control of your company and that the CEO of Duo is not the only one to blame for the enshitification of Duo.
