For three hours, they gave everyone access to create videos with Sora, some of which could very well be art. Not only that, but the form in which they did this and the statement they made could also be considered art. I think they've done well here.

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.
