Why not organize a worldwide protest where every participant produces and shares Art denouncing generative AI? "AI might produce single pieces but this collective work, this is what AI can't do" and so on.
What they're doing is so weird and ineffective in contrast, it baffles me.
Ah yes, a feel good protest that can be completely ignored by everyone, especially OpenAI. Even better, maybe OpenAI could fund it? That way they get to claim they hear the protests but they don't have to actually change anything.
In their statement, they make it clear that they're not opposed to the use of AI in art: they're opposed to the abuse of artists to pretend that OpenAI is doing this for their sake. This serves their perspective better than any juvenile anti-AI quilt could have.
