Are you suggesting that Berkeley doesn’t have the resources to properly add audio transcripts to their course content?
It really feels like the Overton window on disability rights has shifted in the wrong direction.
Just because it’s free, the university has certain obligations from taking federal funding. These laws have been put into place in order to ensure disabled people have equal access to these educational systems.
One way to solve this would have been for Berkeley to charge a nominal fee (perhaps for a limited time as “early access” or similar) that could then be used to pay people that can transcribe the audio.
Instead, a lack of imagination and a lack of empathy leads to these resources being removed, a net loss for everyone.
