The problem is not this specific website or how fast it loads, but that shipping seems to be so much more important than performance, usability, accessibility, or user experience.

One aspect that is not mentioned in this blog post is the enormous impact of bloat (543 KB minus what is really needed to present a text with a nice style, so probably 500 KB) on the environment. News pages, for example, are often bloated with lots and lots of JavaScript libraries and gigantic stylesheets. Imagine how much energy is needed to transmit and process these megabytes, gigabytes or terabytes. All the Co2 that is emitted unnecessarily. Maybe also read this related article.
