This is rapidly becoming a gigantic issue for web-based functions.
Are the OR hosted websites compliant with ADA: section 508, WCAG 2.0 ?
This was a piece of a posting on a bed-and-breakfast site I follow:

We make the sites as standards compliant as we can, and we're always improving -- accessibility is never a once and done sort of process. If you see something that doesn't work in a screenreader, let us know!
Your article was mostly describing text content on the site, though -- best way to handle that is to put a disclaimer in the footer or on separate page.
Someone else asked about this and I posted a message about this:

Summary: ADA, 508 and WCAG don't apply. Don't waste calories on it. Ignore the trolls; they have no legal standing to actually file. Read my response on the above thread.
