The GPL requires all derivative works to be licensed under the GPL also. Most define a derivative work to include copyright-protected elements of an original, previously created first work.
SO, since we have to include the embed code for the Piwik js in every page of any site we’re monitoring, is anyone going to make the argument that the site is a derivative work and therefore must be licensed under the GPL?
I understand that any answer here won’t be a legal answer, but I’m curious as to the thoughts of the people who created and maintain Piwik. To avoid these types of issues, is there any chance that Piwik might move or be dual licensed under the LGPL in the future?
