Bug#692728: Possible GPL violation: Geogebra

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
