Just to chime in with a different perspective, I don't use ChatGPT and have no plans to. Although I totally understand why some may find it useful, and don't have judgements towards those that use it for personal purposes.
For me, one of the many reasons I enjoy DMing is specifically to push myself to improvise and creative. I wasn't encouraged to be imaginative or creative as a child, and so as an adult I often find myself trying to make up for that. As well as letting go of the fear of not being in control, and having fun with making ideas on the spot. It also feels much more fulfilling when something I make up ends up going down well.
Also I tend to like coming up with new concepts that go against the grain, or at least attempt to. And while ChatGPT is good at scraping and spitting out what has been done before, I ambitiously want something that is more surprising or unique than what it offers.
I'm not sure it makes sense to make a call on whether this is the right/wrong decision when we know next to nothing about the specific reasons leading to the removal.
Could be legal reasons, could be something in BWF's contract, or maybe it's purely for the personal comfort for Ashley (which if so, overrides anything else imo). We do not know.
I'm sad to lose the content too. Especially all the insight from the cast, and the BTS interviews. But I also cannot blame them for removing it, it's totally within their rights to do so.
