The article talks a lot about technology choice, but not about given product. I do tend to agree – that SPAs are not necessary, but I would not use this article as an argument.

And if somebody would present this article to me – I would not take it seriously. The fact that author is using very interesting language when refering to React and Angular does not help. I'd love to hear customer-centric or product-centric reasoning. * Don't use SPA because customers hate it when you change entire app on them. * Don't use SPA, because customers of our particular product require faster turn-around. * Don't use SPA, because they are harder to test in our organisation.
