not to say that there aren't experiments worth running. but in my experience (and in the example in the OP's article), the experiment often isn't even worth running. Intelligent people knew from the jump that it was a bad idea. No experiment necessary. Just pointless waste, enabled by hubris and apathy.
My point is that, from the viewpoint of an external observer: we want people doing prosocial work if it's possible, so if there's counterfactuals where they do or don't, we'd rather they do. And the point of taking moral stances on stuff is to press for the attitudes and behaviors that lead to a world that maximize's everyone's safety and happiness and prosperity and whatnot. Therefore it is moral, at some level: a world where the company wastes money on dumb stuff is worse than a world where the company channels that money into value for humanity.
It has nothing to do with the individual's preferences, and I don't begrudge them their preferences either way. My point is that when we're evaluating "letting projects fail" as a policy, the moral angle needs to be part of the conversation, because it does have moral implications. Convincing yourself that it does not is a moral choice: it amounts to saying that you do not feel responsible for those implications in the slightest. That doesn't mean you should turn around and be fully responsible for them, either. As with anything there is a lot to weigh. But completely writing it off seems wrong.
Getting personally attached and emotionally invested in work you get paid for is a risk too. There's nothing wrong with that. But there's also nothing wrong putting your time in and churning out requirements if that's what you want.
