It’s also essential to avoid assuming that any disability might prevent someone from wanting to use your app. Making an assumption like this can result in designs that limit an app’s potential audience. In contrast, when you focus on making each app experience accessible, you give everyone the opportunity to benefit from your app in ways that work for them.

While the whole guide is good, this point is important to me. And it should be important to designers. A disability doesn’t preclude the desire to use your application. Your application precludes my ability to use because of design choices you made.

Everybody wants to find an application to help them work, play, travel, communicate, and more… these are human needs that can be met.
