According to recent news, the University of California, Berkeley has decided to remove 20,000 educational videos from YouTube to address findings by the Department of Justice that these videos do not satisfy accessibility standards set by the Americans with Disabilities Act (ADA). See the university's statement, and this report on reason.com.
While it makes sense to require certain accessibility standards for media when it is created, it seems ludicrous to require deleting or blocking media after it has been created. After all, this helps neither people with special accessibility needs nor those without them.
Does the ADA actually contain passages that can be used to require deletion / blocking of media that do not satisfy accessibility standards? And if yes, what is the motivation for that (assuming one it is documented somehwere)?
