This is fundamentally illogical Florian. Courts are a last resort at best. Before you go to court over something like this you have to analyse whether it is a worthwhile use of scarce resources. That's a tactical decision, and has little to do with the legalities. It's not like trademark where you have a legal obligation to attack or lose either. A million cases can go by where there are technical violations of the GPL that no one finds worthwhile to sue over, a million more where they sue and settle out of court, not one case actually resulting in a judgement, without it having any direct bearing on case #2,000,001.
The question is more complex than a selected soundbyte from FSFE makes it sound? Sure. But when you turn around and claim the exact opposite, you arel being far more inaccurate than they were.
