This seems like overreach. Clearly the law doesn’t cover websites. Why can’t congress just pass a law to make the ADA apply to websites? It’s not SCOTUS’s job to create law.
The law has covered websites for decades. It used to be not that much of a problem because screen readers worked well enough with plain html.
I don't usually find myself scratching my head at SCOTUS. Full and equal enjoyment of the goods and services is the pizza, not the website. The website is just one means of obtaining said pizza.
