I've found sites using Material UI guidelines (heavy use of cards and navbar hamburger) especially culpable to this. Huge gap of greyish whitespace with a hamburger in the left.

Someone else mentioned bootstrap in the other thread too.

Maybe because these Frameworks are hugely popular, their defaults amplify the impact. Definitely these values are tweakable.

Users of CSS frameworks do it to cut corners and follow whatever the framework suggests.
