BTU Ventures, QGEN and ELMED: why tell the US Government, the US Federal Courts, and the Tunisian Government different stories?

All we know about QGEN comes from their own press release and 3-page website. Doing a bit more research, we see other "reflections" of QGEN and its "business" from information provided to, and subsequently published/used by, US government agencies, Tunisian government agencies, and US Federal courts.
