Serving static files off highly efficient, distributed CDNs is a solved problem. There's no "4K blu-rays per second" when you're talking about gzipped, highly cacheable text data.

If github has a million users visiting it per day on a FRESH cache, and all of them have to download at least 10 megabytes of text data (both of these numbers are far too high), you are at ... 0.015 "4k blurays per second". Yeah I think MS's datacenters will survive.

A single-page app is not serving "static files". It might serve an initial bundle, but literally everything after that is dynamically generated. There's no way you could serve those responses via a CDN.
