That's wrong:

"With the latest version of Windows 10 (or 10 Server) and the beta of Docker for Windows, there's native Linux Container support on Windows. That means there's no Virtual Machine or Hyper-V involved (unless you want), so Linux Containers run on Windows itself using Windows 10's built in container support".

In any case, as Linux and macOS prove, there's no need for docker to have to run on a VM. And it seems there's no need on Windows either since 10.

You’re quoting a random blog post from Scott Hanselman and not Docker release notes.

I don’t know what happened with that but I was not wrong and Docker for Windows does still run in a VM: https://docs.docker.com/docker-for-windows/install/

I assume you don’t use Docker on Windows and just pasted the first google result?
