I'd still argue this isn't great news. Brick-and-mortar businesses have exacting specifications that let them how to to meet compliance for things like bathrooms, wheelchair ramps, etc. What we've got now is "follow WCAG 2.0 and stay clenched."

Domino's argued that if ADA does apply to online spaces, Congress should amend the law to say so, and to give us some guidelines on what merits compliance. Right now, it's like we're all just arguing over which house rules are the "right" rules in a game of Monopoly.

Section 508 is not enough, because that specifically applies to government websites only. If we treat ADA compliance as if we were playing a Euro board game, then following Section 508 (and by extension, WCAG 2.0) doesn't mean anything because it's not what is specifically in the rules.
