Nowadays, the landscape is way different. There are just so many "normal folk" on the internet now that content is being consumed at an alarming rate. There is so much stuff on the internet now, that even Youtube videos have become disposable. Most of the stuff that people read and watch now is consumed once and then never visited again because there's just not enough time to revisit the insane amount of content we're exposed to.
Nowadays, why does it matter if a website is made "brittle" if the content isn't going to matter in a few months anyways? And if you do want to archive something for later, shouldn't the words on the page matter more than the code behind it? After all, if a user 12 years from now wants to read your article, all they're going to want is your words and pictures. Code is always brittle because new technology makes everything obsolete.
