Insightful article. I have to confess I never realized the accessibility situation was this bad.

I also want to highlight this excerpt from the comments:

Making things accessible isn’t hard technically. But it requires coordination and people to care about it enough to work on it at the expense of other features. If [I] developed an application on a team and said I had ‘one security guy that works on that stuff as long as it doesn’t interfere with the rest of our work’ I’d be dragged over the coals and have my project forked by the public.

But with accessibility? There’s really no sense of priority or urgency despite it being broken for years and not putting much effort in to fixing it.
