The article is not for technically minded people who would like a lucid explanation of the math behind the result? Because they're pretty clearly trying to hit that target, and frequent interruption of that kind of exposition works against it...
It could've easily been split up in different articles covering different aspects. It's not only lazy, but it doesn't account for what's going on in the world, where attention is super scarce.
It does sometimes feel like it's only there to bulk out the article.
