I mean, this is a humor community, I don’t think anyone is necessarily trying to make a rational argument here.
In particular, the audience here are techies, so we’re usually familiar enough no matter the design, and we probably view enough webpages per day to get bored by the same designs over and over.

But to make a rational argument anyways, user experience isn’t just how easily a user can use a webpage. Experiencing beauty or creativity also adds to the experience.
And sometimes a novel design may be more intuitive or usable than repeating the same thing indefinitely. For example, those icon+text items never felt particularly read-worthy on any webpage.
