I can't agree with this article at all. Having an JSON API and a small web app bundle that you can deliver with a highly-available CDN removes a ton of scaling problems related to SSR and gives a clean separation of concerns both from a managerial and architectural standpoint. It also makes testing dead simple: you just make contracts on what the response bodies will look like and just feed mock data structures into your stateless web app. This allows the API team to make changes to the API layer with confidence that as long as they don't change the contracts with the web app, everything will still work.
