Hard disagree. Tools can absolutely be blamed or otherwise regulated on account of their affordances. You're very close to the "Guns don't kill people, people kill people" argument.
I struggle with the framing of generative AI as an a11y tool as well. I understand that it may serve this purpose, but it's much more than that. Generative AI deserves scrutiny for being such a powerful disinformation tool, for driving massive power consumption and for perpetuating harmful biases.
Also I don't see what you're trying to achieve preemptively calling anyone who disagrees a reactionary... Look, you've been posting a lot of hot takes daily for a while now and I feel like maybe you'd profit from reading and reflecting on things, take time to dig into stuff? Right now you're just asserting one thing after another as fact with little to support any of it.
