[Zope] Zope Products and proprietary software

[Marco Bizzarri]

Hi all.

I would like to know if someone can provide infos on the following topic:

we have developed OpenFlow, which is released under GPL.

A company is distributing a proprietary product based on Zope and OpenFlow.

I suspect that if they want to do so, they should have a different
licence from us.

Can someone provide further insight?

Regards
Marco
