Except it hasn't. The U.S. legal system is based on precedence (common law), and other than a scattering of local Title III judgements (Long v. Live Nation Worldwide, Inc., Haynes v. Hooters of America, LLC, Winn-Dixie, Blick Art) there is no concrete or shared understanding of how ADA applies to e-commerce.
I welcome all these lawsuits, for no other reason that we'll reach a consensus sooner-than-later on compliance.
