I think it's likely that US law will continue to find training on scraped, unlicensed data to be legal.

That doesn't mean much to the many people I know of who refuse to use a technology that they see as being unethically created using the work of others without compensating them.

I continue to hope that someone will train a "vegan" model on licensed or out-of-copyright data so those people can experience the benefits of this class of technology.

(I compare them to vegans because, like vegans, I think their ethical position is credible and has merit even though I do not choose the same ethical framework for myself.)
