Unfortunately (for those impacted) accessibility has been rolled into DEI and called DEIA and the executive orders included accessibility in their revocation. See https://www.whitehouse.gov/presidential-actions/2025/01/endi... for an example. You'll see revocation for both DEI and DEIA, where the A stands for accessibility.
If they wanted to, they could have focused on DEI, but they intentionally and explicitly added accessibility to the conversation and are impacting those programs directly.
