It replaced expert with “people that know how to do that”, which probably makes sense for the target audience.

(If you’re illiterate in the US, it’s probably because of choices you made, and those choices are correlated to listening to news sources that vilify experts.)

But, yeah, it loses nuance.

Also, I’d argue that literacy is less tied to written language these days than language comprehension, and the ability to articulate yourself.

Back when books were precious those two things were highly correlated. Nowadays, not so much.
