Ethics aside I think the reality of the world we live in is that everything that touches the internet will be ingested by a machine learning algorithm. I do not see any way around that.
Having your work widely distributed in a way that makes it accessible to humans means also offering it up as a sacrifice to the AI overlords to train on and regurgitate.
I would publish my work regardless of this fact knowing that in order for it to be enjoyed by others or for me to get any recognition at all I have to let go of complete sole ownership of the ideas (or at least the ability for me to defend these ownership rights over the ideas).
