psKonfigurator - licence question

I found this promising extension in 3 places:
exchange.oxid-esales.com/, oxmod.org/ and http://www.proudsourcing.de/
On Oxid eXchange it is listed as PE and EE version only. On Oxmod and on the developer website they write that it is also available for CE.

And now I am confused about their licence. This document can be downloaded on Oxid exchange:eulafile
When reading oxid-esales-gpl-v3-faq I get the picture that extensions for Oxid CE are published under the GPL.

And now my concern:
If GPL does not cover this extension, then - based on their licence - we are not even allowed to translate it into another language. See subsection 4, point 2.

:frowning:
What now?
