That is entirely intentional. It is still possible to read. At least short wods, and the longer ones you recognize, and can infer from context. The jumping text is mostly distracting.

I'm dyslexic but I have no trouble reading, I just flip letters and numbers around while they are stored in my head primarily. I dont look at individual letters as much the shape of words and context clues so changing a letter or two doesn't matter. If this effect was about half the speed I might get though the article without noticing.

I'd love to know how people try and mitigate thier LD. https://news.ycombinator.com/item?id=11224017

I think one of the factors you are missing is that we haven't had dyslexia all our lives. We have read the unscrambled version so much that the scrambled versions rarely deter us from reading at normal speed. But a real dyslexic never had that chance so their struggle is far greater. It's like when you come across words you don't know or can't guess. Even when you stare at the word for quite some time, you can't make sense of what it is.
