The UC Berkeley decision:
- The letter from the Department of Justice to UC Berkeley (PDF). Dated 2016 August 30.
- Berkeley's first statement
- Opinion: "[T]he government should not set up a dichotomy between ‘access for all’ and ‘access for none.’"
- Opinion: "Stop the excuses already—these requirements aren't new"
I'm not a lawyer, but I think this decision basically says that in the United States, even if you're giving away free stuff, the Web Content Accessibility Guidelines 2.0 are the law of the land. You must implement everything in Level A and Level AA.
The guidelines are things like:
- 1.2.2 Provide captions for audio and video.
- 1.4.1 Don't use color alone to convey any important information.
- 1.4.3 Make sure the contrast between background colors and text is sharp (4.5:1 or better).
- 2.3 Don't give your users seizures.
You find a lot of the same advice if you look up basic Web site usability, or basic search engine optimization. Everyone benefits when you do this stuff.
