There is no such concept as STEM bros. Science community has its own problems but being generally anologous to tech bros or fintech bros is not it. Being very strongly curiousity driven, they may indeed be oblivious to how something fucks up other parts of the society but that is very far removed from trying to abuse technology to gain billions. Not that there isn't an intersection, there is, but not big enough to warrant a generalization. In any case if the issue is billionaires fucking up research for money, they will more often be on your side against the billionaires then not (open science movement was one such reaction). But they would rather free AI from billionaire domination then reject it out right.
