That sounds very frustrating. More frustrating than me explaining to senior mgmt why we need to spend money on a11y.

Your example is a great one, but aside from audio and visual problems, a11y covers things like cognitive deficits, which, for some, make watching and learning from videos difficult.

Good on you, more people need to be making a fuss about this.

I actually wrote Chris Croyier about a small snippet of example code on his site (CSS-Tricks) that didn't follow a11y best practices. He replied, and updated the code! Nice guy.
