I hope you know that's not a very strong legal precedent, which is why it keeps getting appealed to the Supreme Court from various jurisdictions. You speak (or seem to hope) as if the law is clearly on one side, which it isn't, at least not that strongly.

There is contradictory case law (like Southwest Airlines 2002) that says the ADA does not extend to virtual / online stores.

Companies are policing themselves on this issue out of liability to be sued, which is a far cry from a declarative right to have accommodations online. It is not that certain.
