I think you're missing Uber's actual concerns. Uber has built its business skirting the laws on taxis and other transportation companies-- exploiting a loophole. If the ADA law gets applied to them, it'll be a legal precedent for treating them like every other transportation company. So now they have to fight it- not because they care about people with wheelchairs, but because it's an existential threat to the foundation of their business. What makes the situation interesting is that Uber could have avoided this whole fiasco by being ethical in the beginning, and making "you have to help people with disabilities" a part of their new-driver training. Then this would never have become a legal issue, and they wouldn't have the public shame of fighting against people with disabilities, or the threat to the core of their business.
