It's a political thing. I've lobbied for accessibility, including explicit support for screenreaders, at every company where I've worked since ~2007. Politically though, I'm wholly against laws to require this sort of thing. If a company wants to alienate 15% of their potential market (the blind and colorblind), more power to them.
