Also the EU and technically a lot of US sites that provide services to or for the government have similar requirements. The latter is largely unenforced though unless you're interacting with states that also have accessibility laws.

And honestly a ton of sites that should be covered by these requirements just don't care or get rubber stamped as compliant. Because unless someone actually complains they don't have a reason to care.

I kind of thought the EU requirements that have some actual penalties would change this indifference but other than some busy accessibility groups helping people that already care, I haven't heard a lot about enforcement that would suggest it's actually changed.
