Creating accessible websites is a pain. And doing it properly is expensive.
There's many screenreaders and they can get expensive. They also can have quirks of their own. UK government accessibility blog is a good resource on how to create accessible websites and forms[0].
I also tested accessibe.com's frontpage to see how accessible their own site is. For this test I used Google Chrome with Lighthouse[1] accessibility testing set to desktop. Lighthouse reported a score of 84/100 where bigger is better.
Some links don't have text, but an image with an alt text. Some text colors are not WCAG contrast compliant. The viewport maximum-scale is limited to 1, so the user cannot zoom on the website on a mobile device.
I also ran another accessibility checker called axe[2]. It reported 88 issues. Funnily enough, on the blog post they slammed icon fonts such as fontawesome or icomoon, and they themselves use icomoon without a screen readable text. Most of the issues were related to links not having discernible text, elements not having sufficient color contrast, and lack of landmarks on the page content.
