A few days ago, I’ve expressed my concern about the attribution clause (not longer available on their website) added to the MPL 1.1 in the Alfresco ECM. Today, Alfresco released the Alfresco 2.0 Community Release of their ECM under the GPL 2.
Their branding is now so huge that the attribution clause became obsolete, they effectively started to market their software before they had any huge install based and fully functional packages (thanks to the well known VC and their experienced team).
