Open Core
It seems this sort of legal arrangement (open source + copyright assignment with rights to use proprietary licenses) is called "open core", which might warrant another article. Some links:

(Perhaps the first definition of open core) 'In this way, it is clear to customers that there is a "core" open source product that is GPL, and there is also additional high-value available as add-on features for purchase. So who is using "open-core licensing" successfully? Well, Sugar, Jaspersoft, Zimbra, and Talend to name a few of the rapidly growing list. Even MySQL may already be in that category' - http://alampitt.typepad.com/lampitt_or_leave_it/2008/08/open-core-licen.html —Darxus (talk) 01:26, 3 January 2011 (UTC)
