I shouldn't have used the term "business," because that made people think that I was referring more to economics instead of "doing the right thing even when the right thing is slightly more expensive." Look, UC Berkeley is a public university and they have to adhere to certain rules around disabilities and accommodations. It's well established law at this point; the ADA is 35 years old. They should know this, and they should be able to comply. To take down the videos suggests laziness and ignorance on Berkeley's part.
