Look, I can be critical of slave-owners even if that slavery is legal. My qualm is with both them, personally, as individuals, AND the system of slavery as a whole. I would go so far as to say that owning slaves is, yes, abusive, immoral, and unethical.
I realize the DMCA is on a vastly different scale than slavery, I’m just trying to communicate the concept that “legality has nothing to do with morality”. Please stop explaining the law to me. I know what the law says.
