To be honest, I didn't know the Stocks app still existed.

I feel as if the article misunderstands the point of brutalism in architecture. Brutalism is an expression of confidence and commitment through cement and other more permanent materials to bring a style that others may not like but serves the purpose without bells and whistles.

A lot of 'brutalist' websites are actually just parodies of the past. For an actual version of brutalism brought into websites, you would need to transfer these elements into web design. This is brutalism - (http://motherfuckingwebsite.com/).

Adding flashy GIFs and purposely making a website unappealing is not brutalism.
