I'm tired of waiting for industry organizations to respond to AI issues. Working draft of my own is here: http://neil-clarke.com/ai-statement/
I guess scraping it off the internet and using it in an AI confabulation mill is going to be legal because it hasn't been made illegal.
@henry @clarkesworld you may argue quite a lot, and it is up to the competent courts to decide (they will apply the national implementations, not the convention directly).
But to give you a more concrete answer, I doubt that that in itself would help you: in the cases you've cited there is a public performance, connected to political views. The training is a very silent act.
We'll have to wait for cases. One of the better overviews of what's going on: https://www.youtube.com/watch?v=h4ax8twEwgw&t=390s
