It's frustrating, but then again, 99% of the web is frustrating.
While I'd like to hold governments to a higher standard, I think we all know that if anything, they're always behind the ball and need even more help than an average site built by developers who keep active in developer communities. Not that it's always the developers: I heard bits of the horror story of the healthcare.gov... zomg, I wouldn't want to have been on any of those teams working on that.
Also, the requirement is "fulfills section 508", which I've heard is getting an update but still on the books is WCAG1. I've seen sites "fulfill" some section 508 checklist technically, but I wouldn't have called the very accessible to actual humans.
