Supreme Court allows blind people to sue retailers if websites aren't accessible
Blind programmer here. Just a glimpse of my life.
Blind people have to live in an environment where X% of web sites and programs are not accessible, where X varies somewhere from 20% (for web sites) to 50% (for desktop applications). That's just my approximation of the state of accessibility these days.
Now imagine that you live in the world where you don't know which printer or wi-fi router to buy, since maybe half of them you won't be able to use.
Imagine that you cannot order from some online stores. You cannot fly certain airlines. And apparently you cannot order some pizza online.
Worst of all you don't magically know whether a web site is accessible or not. You just go to web site and try it, spend some time to learn the layout - it typically takes blind peple longer to familiarize with new web sites, spend thirty minutes to fill out the details of your order  and then when you try to click the submit button, you figure out that it wouldn't click for some reason. Being a developer you open HTML code just to realize that this is some weird kind of button that can only be clicked with the mouse, but not a screenreader. But hey, your screenreader can route the mouse cursor to this button and simulate a click. So you try a real mouse click and it still doesn't work for some reason, and I have no idea why. Finally, you give up.
I hope I managed to convey a typical sense of frustration with a web-site that is not that accessible. I do  get arguments of other people that it might be hard for small businesses to make their web sites accessible. and I don't know where to draw a line, but I need to say that Domino's is a large enough company and even though I hate counting other companies' money, I must say they're big enough to be able to afford to make their web-site accessible.
