It's not being "simply mistaken", it's a calculated belief. Someone might think it's a moral act to fund, say, ecoterrorists to bomb the headquarters of a major oil company, believing that the loss of life is worth it for helping the world by destablising the company. We might disagree, and consider that highly immoral. That's an extreme example of course, and in this case the worst that can happen is some loss of money, rather than loss of lives, but I hope it illustrates my point: them choosing to pay people to think about AI, rather than giving that money to other causes, is a moral choice with which I disagree.
