(a) accessibility is about all disabilities, not being blind

(b) overall “significant” disability levels are more like 16% [1]

(c) the 16% is at any one time. The chances of us all experiencing disability during our lifespan are much higher

(d) accessibility is a legal requirement for many systems in many regions. Even if you’re not engaging with a region with a legal requirement yet, do you want to have to build from scratch when you do?
