That at the end of the day, Uber sent a woman into terrible situation, creating a bunch of externalities that society has to bare. Society should have the right to identify those externalities and bring the companies attention to those externalities. If the company says "not my problem" the public should get to decide if they want to allow a company to blithely foist those externalities onto society.
They have a legal argument why they arent responsible, but that doesnt mean they are socially responsible to its users, shareholders and other stakeholders.
Even then, the courts have made their order, so it looks like their arguments were legally insufficient.
Its hard for me to defend a system that blatently hurts the disabled then tries to argue a loophole around the ADA. They even have a link declaring how much they care about providing accessibility https://www.uber.com/us/en/about/accessibility .
All this lip service and they wont take responsibility for a blind woman being stranded multiple times, because she was stranded by their "contractor".
