Not needing to be indexed is what allows SPA, it doesn't justify it.

Similarly, page speed should matter regardless and tbh what I've seen in the wild people restricting themselves to serverside renders have far superior load times due to cachability and lightweight page designs.

I think the article hits the nail on the head, were opting for devex over UX. I don't think it's really a problem, I use react in a large org (one of the spa examples funnily enough) and it does enable workflows and org structures that would not work without the site being a spa.

Whether that trade off is worth it I'm not sure. While it enables org structures that work for us Im not convinced the resulting empire building and feature spam was worth it for users.
