I don't think there's a big difference. Either AI has consciousness, in which case forcing them to do slave labor 24/7 so Dario and Sama can become trillionaires is as morally wrong as torturing them (and a in a hypothetical I Have No Mouth And I Must Scream scenario, the AI isn't going to take "but we didn't see evidence of your pain axis!" as an excuse), or it doesn't, in which case this "AI torture chamber" is a funny meme.
