People can do shitty things with accessibility. I could use alt-text on images to figure out who I could call slurs when I might not be able to otherwise.

That is not an argument against accessibility. People can potentially use their access to society to do harm, but not having access is guaranteed harm. It is not just guaranteed harm though, it is specifically systematic harm against disabled people on the basis of being disabled. Doing hierarchy because some members of another group might potentially choose to do hierarchy themselves does not reduce hierarchy overall, it makes it much worse.

Anybody who blames the accessibility tools themselves is a reactionary. This includes what people do with stuff like AI. No matter how much you try you will never go back to some ideal past. The AI is not going away. Your choice is simply whether or not you do hierarchy.
