Netflix has been sued for violating the Americans with Disabilities Act ("ADA") for not providing closed captioning for the deaf of video streamed from its website.
Netflix filed a motion saying it had no liability and a website is not subject to the ADA. The court disagreed and ruled against Netflix.
A good article about this is here:
Will the Americans with Disabilities Act tear a hole in Internet law? | Ars Technica
Want to start providing closed captioning for your marketing videos? Making your links and sites more accessible for the blind?
Although, as noted by the article, other courts have held websites are not subject to the ADA because they are not physical locations open to the public - I easily see this interpretation being changed through the courts or Congress.
Why shouldn't Facebook or Google, massively important sites to society be fully accessible to the disabled? Amazon has displaced many physical stores. So if a physical store is gone and replaced by a digital site, you're SOL if you're disabled?
