UC Berkeley was the subject of a Justice Department investigation which stated they weren't in compliance with the law, but never actually sued or subject to a court order to take down anything. They made a unilateral decision.

They decided not to pay for captioning, image enhancement or audio descriptions for their lectures for old content, even though the justice department letter said:

"UC Berkeley is not, however, required to take any action that it can demonstrate would result in a fundamental alteration in the nature of its service, program or activity or in undue financial and administrative burdens".

They could arguably have fulfilled their requirements by working to update material based on actual demand, and having a process to request updating such material. Court ordered consent degrees are negotiated and approved by a judge, and they could have attempted to negotiate something to address the complaint.

UC Berkeley is a public institution, with expenses paid for in large part by federal and state funds, and those funds come with requirements not to discriminate on the basis of disability, and instead of actually addressing that discrimination in a meaningful way for their content, they chose to simply stop providing the service. You can have your opinion on if that's the right decision, but they weren't forced to make one decision or another.

And per UC Berkeley, it wasn't just the Justice department letter, but also online "limited use" and to better protect instructor intellectual property from 'pirates'". https://news.berkeley.edu/2017/03/01/course-capture/
