UC Berkeley was never sued. They never went to court. They seem to have broadly agreed with the USDOJ and decided to just remove the content. The case hinges on the public accommodation part of the ADA. It has not been decided in any court whether or not the public accommodation clause pertains to freely distributed content by a University with no economic incentives.
Things like netflix have been ruled to be public accommodation (as you might expect, it is a company offering a service to the public). And two universities are fighting this right now (harvard and MIT) in court. You can look it up. The latest I have seen is it was ruled the case could go forward because MIT and Harvard did not give good reason to dismiss the case (it seems that ruling hinged on the fact that you can't dismiss a complaint because the defendant has a great defense, only because the plaintiff has no standing). I'm not sure where those cases sit now as that last ruling was a year ago.
It could easily be ruled that freely distributed content by a university in an unstructured way (here are all the videos, the best we have done is organize them by course) does NOT need to be ADA compliant but things like MOOCs where a person can get some sort of certificate does.
To answer your question, the photo can't be banned. A disabled person can bring a lawsuit against a museum or display hall for not including some kind of access (I think).
