> TL;DR: "We tried to make a responsive web app act like a native app and it didn't work because it doesn't work, and that makes me a grumpy goose."

That's literally his entire thesis.

There's been a ton of effort invested in trying to make web apps capable of competing with native apps, and his point is that it's still simply just not feasible. It's cheaper — and more importantly, costs are more predictable — to develop a native app for every platform you want to support, than to develop a single modern webapp of equivalent quality.
