It's impossible to have access for all. Reductio ad absurdum: illiterate and mentally handicapped people exist, therefore, we should burn all books.
There's likely a fairer way of doing this instead of denying access to all for the sake of a few. For example, a JIT system for accessibility. A disabled person, if interested, could make a request to have material translated to their preferred mode.
And when it's prohibitively expensive, you really prefer just not giving anyone access?
The amount of video that is being produced and uploaded today makes a requirement to put traditional closed captioning on each one absolutely laughable and ridiculous. It's telling that the requirement was dreamed up in 1990, probably by people without a lot of vision for how cheap bandwidth might become and the amount of content that would be produced and shared within a few decades.
The public is the loser, here. Institutions like Berkeley will have to pull down high-quality content, but amateur content isn't affected. So the overall quality of content available to the public just got worse.
There is no way in which this is a win for the majority.
