This is wishful thinking. If an employee is inclined to follow the innovation, it's clear where they'll go.
But otherwise, the point you raise is a good one: this is about the charter of the board. Many of us are presuming a financial incentive, but the structure of the company means they might actually be incentivized to stop the continued development of the technology if they think it poses a risk to humanity. Now, I personally find this to be hogwash, but it is a legitimate argument for why the board might actually be right in acting apparently irrationally.
