That is more or less correct, however you may wish to consult Atanu 
Ghosh <atanu at xorp.org> if you have specific questions about the license.

I'm not aware of other open source implementations of router-side 
IGMPv3, although I believe there was one old Linux snapshot of host-mode 
support which was bundled with router-mode; probably the one you found; 
I couldn't reach that URL.

The most widely deployed implementation is probably Microsoft Windows, 
and that is not open-source to my knowledge.
