Hello, >From it last few releases, geogebra is released under GPL with a non commercial clause.
Besides the fact that it seems invalid, it also ships Jlatexmath (which I co maintain) which is published under the GPL v2. As you can see on the Debian thread ( http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=692728 ), we contacted and exchanged with upstream. Since they didn't move, we contacted them privately to get more information and they replied with: "we've had our licence etc details checked by an experienced legal team and it's OK. Hopefully this is clear: http://www.geogebra.org/cms/license#FAQ" <http://www.geogebra.org/cms/license#FAQ> In particular, first sentence of their license ( http://www.geogebra.org/cms/license ) is non-free "You are free to copy, distribute and transmit GeoGebra for non-commercial purposes" Do you think their "experienced legal team" is right? Thanks Sylvestre
