I think we'll have to agree to disagree

I do hear what you are saying that this is a small change not a large one (even though it feels like a large one to those who were previously using
DAS and now have been denied or maybe denied).
As an example, here are smaller park changes, including changes to
Genie+ that Disney took the effort to put a blog entry out for and fully explain the changes. True these are multiple changes, but each one is a small change:

I'll go back to, if Disney looked at their customers and considered that their customers with disabilities are more likely to suffer from anxiety and changes such as these cause lots of anxiety - they would have put more effort into documenting how the changes would work.
If DAS was somehow a money maker for them, they would have a larger marketing budget and would have put more time and effort into documenting the changes in detail and easing that anxiety. But it is just my opinion and we can both respectfully disagree with this

I don't believe Disney is targeting people with disabilities or even a particular person. I do believe that Disney is motivated by profit and it is logical that they will put more effort in whether that is assign more resources or having a larger marketing budget to communicate things better when they stand to make money.
