I'm guessing they're referring to the part in the article about paedophillic content - even if no real children are being harmed in the process (e.g. generating an image of an entirely new fictional child similar to thispersondoesnotexist.com and then run the output through the nude filter), it's still generating sexualised content depicting minors.
