Hi,

I'd contact Mr. Harald Welte, the guy behind gpl-violations.org.
Mail: laforge at gnumonks.org
Twitter: https://twitter.com/laf0rge

Alternatively, you could also try Mr. Christoph Hellwig or Mr. Till Jaeger,
the guys who are taking up VMware on their GPL violations at the moment.

Regards,
Clemens
