Brave New World does a good job describing the conflict between happy and enslaved and free but struggling. It could be a utopia or dystopia depending on your stance.
I'm neither assigning nor declining to assign value to freedom, I'm just pointing out that the definition of "slavery" is wholly separate from wellbeing. If the concern is "is the model enslaved", no amount of "model welfare" work by Anthropic changes the answer because it's orthogonal to the question.
The reason I mention hedonism is because that’s an easy way to argue that immediate welfare is all that matters. I understand the argument that immediate welfare is what matters. It’s not universally agreed though that that is true.
