But it really opens a can of worms. What's a place of public accommodation? With brick-and-mortar, it's easy; if you have a physical location open to the general public, it probably qualifies. But on the web? Does my personal website count? What if I sell t-shirts on it? What if I don't sell anything, but have forums where the public can discuss things? What about a site which is primarily about communications, i.e. speech? Does a requirement that you put ARIA labels on things amount to compelled speech?
What if accessibility standards change? Am I compelled to upgrade my site?
This issue is a lot hairier than the court imagines. Does the court really want to get into the issue of which websites need to comply and which don't?
