So it's really called brutalist web design? Someone mentioned it to me on IRC but I thought it was just the adjective he used to describe the https://motherfuckingwebsite.com. Had no idea this had turned into an entire design trend.
People conflate brutalist design with user hostile UI. If a site doesn't wrap properly one a decent phone, it's user hostile. The brutalist moniker mostly means low-JS and less formulaic sites that aren't SEO optimized to the bones.
