I think it is a bit naive to think they released those videos out of altruism. It is free marketing for them and a way of distinguishing their brand, funded by students, the state, and the federal government. They had an office dedicated to helping professors make course materials, to include resources for subtitling course material and QA processes for ensuring accessibility. For whatever reason, the university did not require use of the office and the professors did not use it even though it was there. The DoJ report I linked above has additional information on that. I may not be remembering accurately, but I am fairly sure the material Berkeley posted on edX at the time was just recordings of their actual lectures given to on-campus students and/or recordings they were making/were made for online classes (that were paid for). In other words, they were not going out of their way to record these lectures specifically for MOOCs.
