Quite interesting, but doesn't speak to the creation of fonts specifically to make reading harder for the disabled. It even says evidence that Calibri is easier isn't conclusive. Doesn't say anything about whether any font was created to make reading easier or harder for anyone.
Awwww was baby Rubio triggered by the mean old font? It's ok. The fonts can't hurt you. You're very brave.
Can't let the spotlight fade, gotta defeat another straw-man...
