We moved the repository because the first task of the Moby project is to break up the Docker engine monolith into smaller components, and spin them out into separate repos. We started doing that with libnetwork, containerd, distribution etc, but we are not done yet. docker/docker is where that monolith lives, and where its maintainers work.

Once the componentization is complete, Moby will be an integration repository, with the tools necessary to combine upstream components into a complete system. We will use it to assemble Docker, and other system builders can use it to assemble alternatives to Docker.

The Moby project as outlined sounds great.

This redirect will probably prove disruptive, confusing, and frustrating to a lot of people. I assume it's too late now, but you might consider asking github if you can revert to allow github.com/docker/docker to remain as it was for a time, and allow moby/moby to gradually pull in the actual code.

Perhaps there are technical reasons this would be infeasible. The github landing page serves as valuable marketing, branding, and social-proof (stars, etc) even if most folks don't end up looking at the code there.
