Yeah I agree the hyperbolic sentences are over the top. The only way for anyone to reliably get 100% uptime is to use two or three cloud providers or their own dedicated boxes somewhere. Even AWS don't provide 100% uptime guarantees. Though I think the author's underlying point that good design should lead to fewer/smaller planned outages. However, his statements are over the top in the extreme.

Two days down, by a world-scale provider, is also over the top.

Nobody expects 100% uptime. They also don't expect 100% down for days.

Understood. His main point is that no cloud provider should ever have any downtime which is idiotic and no reputable company would ever promise zero downtime.

True story. Amazon is all about telling people to plan for failure and building around it in your architecture.

Also, nearly nothing will give you 100% uptime. That's fault tolerance and almost nobody has it.
