This doesn't seem fair to say. Linear is special even among SPAs; it's by far not the norm. No one said "ban SPAs and remove javascript from the browser".

Linear's speed comes from being "offline-first", but I challenge you to name almost any other product in common usage that does it that way. It's just not common. On the other hand if I want to buy tickets I'd rather most of that website be SSR and do SPA where you actually still need it. Or forums, news sites, blogs, and informational sites.

There is so much out there that would be better developed with SSR and then use CSS to make it feel SPA-like than to actually be a SPA.

The article's title is it's time to kill SPAs
