The state of accessibility (as a design goal; as, finding the point where it critically improves the situation for some, yet is beneficial for everyone) in tech

The state of accessibility (as a design goal; as, finding the point where it critically improves the situation for some, yet is beneficial for everyone) in tech is generally awful. It's sad that this doesn't look like it's a priority to Apple. My only hope is that I'm wrong, that the affordances are actually more than OK once you use it, and that they've done loads of usage testing and found that it works better for the majority of people, as well as those with greater needs.
