Just as a SPA won't solve all your problems without any trade-offs, getting rid of a SPA framework also won't solve all your problems -- you'll probably need to re-invent some wheels and then discover that your new solutions are hard too.
I think it's good to have a healthy dose of skepticism about new technologies. But it's also important to understand their value and not to hate them just because they're hard. I like that the author tries to find this ballance. Though, honestly, from my own experience, I would rename this title to "You might not need a single-page app."
More than once, I've tried to build something without a SPA framework only to realize that if there is any interactivity at all, it's often just simpler to use a SPA framework in the first place.
