I appreciate "neobrutalism" is really a very different movement to architectural brutalism, but I'm not sure how the first examples the author provides [1] can really be compared to the original brutalist movement at all. Sure, they use heavy contrast & minimal colour, but to my understanding at least, the most important aspects of brutalism were its focus on exposing the raw materials with which buildings were constructed, its geometry, and its overall minimalism.
To me, examples like [2], [3], [4], [5], [6] would be the closest the modern web can really get to "brutalism", but for some reason I can't imagine design blogs will be fawning over them.
