With respect to GNU developers openly and publicly endorsing slavery (phew, that's a hell of a statement), I think white folks like me who are not under direct threat of that brutal institution and who do not bear the generational results of that violence to pause for just a moment and sit with that.
In particular, I think we need to sit with how that interacts with eugenics-fueled AI boosterism more broadly.
I have a personal policy of not comparing things to slavery, because nothing we have seen in modern-day American culture can compare to the sheer scope of the violence that was slavery. Nothing. Full stop. The violence of slavery simply cannot be overstated, it's not possible.
I think it is also true that regardless of what harm boosters actually perpetuate in the world, their stated *goals* are to replicate that violence.
