I've seen Brutalist design being mentioned a few times here and it always shows this website gallery, I am no specialist, so I wonder, is this what brutalist design really is?

Quick Google search explains that brutalist architecture is about creating modular elements representing specific functionality often sacrificing aesthetics.

A lot of the sites on that gallery are ugly just for being ugly, they have no functionality and use different types of animations or constructs to just make something unconventional from common website aesthetics, I get why, but it feels like the word brutalist was borrowed here and is applied in a very different way.
