Also from that thread:

Moby = open source development

Docker CE = free product release based on Moby

Docker EE = commercial product release based on Docker CE.

Nothing is dead; and everything that was open-source remains open-source. In fact we are open-sourcing new things.

So essentially the difference between Chromium and Chrome?

You are better off looking at Oracle, the difference between (say) MySQL Community Edition and MySQL Enterprise Edition, and the relationships between MySQL and MariaDB and Percona.

No, that would not be accurate.

The difference between them is like

Redhat Enterprise Linux (Costs Money, Enterprise Supported)

vs

CentOS (Community managed, community supported, Libre Free)

CentOS comes from RHEL, while Docker comes from Moby. So the correct parallel is Fedora-RHEL or Wildfly-JBoss.
