Agreed. Not doubting that many people have illnesses and disabilities which certainly make theme parks harder to navigate. However, DAS went above + beyond what was required, which I think spoiled a lot of people and also allowed for a LOT of abuse from people who didn't need the service.
Now Disney is saying DAS is only for people with severe developmental disabilities that make waiting in a traditional queue impossible 100% of the time. For everyone else, they're offering a couple of other options which are short of DAS and aren't as convenient, but if you have a true disability you'll appreciate them (eg being able to step out of line with a family member, while the rest of your family continues the queue).
There's also a whole lot of hang wringing about some of the guidance Disney is providing. Lots of these complainers have things like POTS or heat-triggered illnesses, which I'm not doubting is awful. So Disney encourages you to visit during cooler times. This is helpful advice. Why would someone even consider traveling to central Florida in the summer with an illness that makes you lose consciousness in heat? Same thing with encouraging parent that has a child with ADHD or another such illness to practice waiting in line at home. These things could perhaps seem patronizing but they are helpful pieces of advice.
If you find that the accessibility options aren't as convenient for you as DAS was, then Genie+ is a worthwhile investment.
Mentioned this quite a few pages ago but think of it like this. Someone with mobility issue purchases a basic economy plane ticket, which gives them the bare minimum and doesn't allow you to pre-book seats or anything else. Due to their mobility issue, they can rightfully expect the airline to provide service to get them onto the plane and have a seat they can sit safely in. Not a problem. But someone who purchases a basic economy with IBS or a similar condition can't force the airline to give them an aisle seat near a bathroom for convenience of being able to make the bathroom on time. They can ask, but the airline may well say "we suggest you upgrade to our next fare class to pre-book a seat." Not too different than G+. Disney is offering the minimum level of accommodations but if you want more convenience you can essentially buy a better fare class (eg G+).
