> It's great to say that if you know where all the strobe effects are in 10,000,000 hours of videos, you could add warnings to the timelines of those videos to help people with photosensitive epilepsy. But unless you have an unimaginable army of people who can watch all that video, the practical way to find all those strobes is to feed the video to a computer, after bypassing the DRM. Otherwise, most video will never, ever be made safe for people with photosensitive epilepsy.

I wonder if there is a case to be made here under the ADA in the US. By making it impossible for someone to use their own assistive measures, and by not providing their own assistive technologies, companies that employ DRM are essentially closing their services off to a significant portion of the disabled population.
