The fact how simple it is to re-implement a large part of Docker because all it fundamentally is a bit of glue code to the kernel is the biggest problem Docker-the-company faced and still faces.

Where Docker adds real value is not (just) Docker Hub but Docker for Windows and Mac. The integrations offer a vastly superior experience than messing around with VirtualBox and Vagrant by hand (been there, done that) to achieve running Docker on one's development machine.

A lot of popular wealthy systems are 'easy' to re-implement. I thought the value was in Docker images? Or is that not how Docker is used? The only way I've used it is to be able to import someone's virtual build setup so I could build something from years ago.
