National Design Studio is unproductive and does shoddy work. They have launched a handful of single-page sites. Many of these are full of AI slop, got caught running illegal trackers, failed accessibility audits, ignore established design standards and conventions, contain little useful information, or are heavy on bandwidth and CPU. They are flashy. They are not fit for purpose.
Seriously, just look at this crap. Fonts so large they become hard to read blurring into existence as I scroll, giant autoplaying video chewing up my bandwidth and CPU, giant useless pictures, a "food pyramid" even harder to read than the one from the '90s, low-contrast colors, not a citation in sight, one picture too small to read that can be expanded by clicking on it with no indication of this interaction, and it looks nothing like any other government website in existence. The total page weight is over 30 megs. Worthless at conveying information, but it looks capital-M Modern (and gives me a capital-M Migraine).

(The information is crap, too, but you already knew that.)
GSA's work was mainly done by 18F. Which was also destroyed by Musk and pals at the same time they destroyed USDS.
What made USDS (and 18F) special was not merely having web developers in the executive branch. It was that they were among the best in the world, and drove standardization and improvement across the entire government. Now we've got AI bros with buckets of eye-catching (eye-melting) slop.
