Title should have ADA in all caps as Ada is a given name. I see the opposite all too often when talking about the programming language Ada where people type ADA which can stand for the American Dental Association or Americans with Disabilities Act.
I expect the 92% number to rise as the number of anti-AI scraping measures and CAPTCHAs that are not compatible with assistive technologies continues to rise.

The tools used by the blind changed a lot in the past 3 years. The era of needing specific ADA accommodations for the blind is probably already over, if challenged in court.
I had to sift through a bunch of different state agency websites before Covid for a job. Most of these websites are nightmares when trying to find information or fill out a form. I can't imagine trying to navigate these sites by yourself with a disability. Honestly, if you're hosting a website on a .gov domain, you should be required to use USWDS (https://designsystem.digital.gov) or something equivalent.
Honestly most of the world is inaccessible by design even the new things. Most people just don't think about the disabled at all and if they do its to talk about what they need and not actually to ask them what they need and include them. Ableism is the most prevalent and accepted bigotry in the world. There is also no movement to really fix this in the modern age, if anything its getting worse in a lot of places.
