The distinction is important because the censor component is just an annoyance nobody cares about - all the interest is in exploring the capabilities of the GPT model.
I suspect this differs considerably between people who want to play with the ChatGPT and (at least some of) the people who want to sell services using it.
I suspect refining their moderation product is one of the fairly important reasons to have public exposure of the combined system for OpenAI. (That and discovering what people do with it to figure out how best to market it and spin it into more specialized products of their own.)
