I don't know, I think it makes a lot more sense to assume that he's a dysfunctional fuck-up who's spending his mid-life crisis taking on a project he clearly can't handle.
I could see many billionaires doing that. But Musk is the same guy who built high speed one-way underground car tunnel with no room for emergency services instead of a fucking train. He doesn't have the capacity for such schemes.
I think it probably scared the researchers too much that the "normal" neurotypical people were less likely to have moral values in any meaningful sense, so they tried (badly) to reframe it as neurodivergent people being bad. That's probably what they're used to believing in general, so they made an argument closer to their comfort zone instead of reporting the facts.
Kind of reaffirming the study, in a way.
When I was on Reddit I watched surrealmemes devolve into me_irl. I'm glad it's back to form here
