The quote in the parent comment seems to suggest that perfectly valid scientific findings should be withheld if there is a possibility that bad people would misuse them. The consequence of this of course would be a complete victory of "Blank Slate"[1] Dogma (because any scientific finding that finds differences between social groups could be misused to undermine the human rights of one group).
And yet the statement never quite explicitly says findings should be withheld only because they could be misused. Rather it says that research that contains contain hate speech, etc. should perhaps not be published. It says authors should consider the potential harm of their research, and so on.
The intended result I think is a sort of chilling effect with plausible deniability. It pleases the inquisition, and at the same time leaves the scientists with a remainder of self-respect. I am not sure how long this delicate truce can last.
