I think that many are looking at accessibility in terms of "am I legally required" or not in order to avoid a lawsuit or some government action.

We see it as a business question. It will allow us to reach a bigger audience. That is a quantifiable plus. And it is not just about blind users.

Many of the changes that improve accessibility, also improve SEO. Some also make the website work better for mobile.

Seriously, this is just good business.
