Not commenting on TFA's content but... It's using:

   text-align: justify;
   hypens: auto;

That is, IMO, underrated. I'm reading this on a M1 MacBook Air: maybe at "retina" pixel density we can, at last, use text-align: justify and have pages looking (nearly) as nice as book pages.

I'm not going to force justification for people on small devices (it looks bad on these) but it sure is pleasant to me on a high-density, kinda large, screen.
