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?
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.
Social media bad, Javascript bad, cars bad, old internet good, RSS good, personal websites good, HTML good.

It's by no means a perfect article, but the general message seems to be that we're not powerless to build the web we want, and you can host your own website, which is still true.
* As a sidenote, people who just say "This." and "Cool." irk me, and I don't want to elicit the same annoyed reaction in others.
