Yep, they are just greedy fuckers.

For every 4Gb memory card that you buy GEMA gets ~2€ because you have the possibility to share files which might be copyrighted.

Btw.: in many cases I couldn't watch a music-video on the band's fucking official channel because GEMA blocked it, so I just downloaded it from the internet.
What kind of shit is this? GEMA is supposed to help ppl with their copyrighted stuff.
