I'm with you. Surprised by the negative reactions here.

A possible piece of the puzzle: I originally read the article on mobile, no issues. Then I opened it on my desktop, and found the design quite jarring. The margins are much too large for my taste, forcing the text into a single narrow column, and the header animations were distracting and disorienting (fortunately the page works perfectly with JavaScript disabled). Perhaps this triggered people?

I really, really, really, really, really, really, really, really, really, really hate the design trend of confining tiny text into a tiny narrow column down the middle of my browser. It's an awful stylistic decision, and this is the petty hill I'm willing to die on. It's so bad that I really can't take a site seriously that does it.

Now, someone's going to come out of the woodwork to remind me, "Well, ackshually, research suggests that it's easier to read text that's constrained by blah blah blah blah" I don't care. It sucks. It's always sucked. It will forever suck. I have a nice 27" monitor, and I want to use the whole thing. I don't want to have to hit ctrl-] ten times just to have text that is readable and spans my monitor.
