They already reversed course on that decision a couple of days later. Trivial to find a source, but Fable is also rather notably not available to the public right now, so it's not actually a relevant threat.
That’s totally unrelated. The post I was replying to claimed that if you create a new account with OpenAI and that gets detected, your whole account gets silently “nerfed”.
That is not in any way related to Fable (visibly) being switched to a less strong model if you’re trying to discuss certain topics.
