That's what I was thinking. Not all the websites look "brutalist" to me, some are okay. But some websites are really brutal and a pain to look at, like this one: http://kioskkiosk.com/ This one is a joke.
Brutalism is not supposed to be painful or unpleasant, just brutally honest. Brutalist buildings look like giant blocks of raw concrete (béton brut), because that's exactly what they are and no effort is wasted on hiding that fact.
