Nonsense. If Samsung gets away with this it will have implicates for all agreements of this kind. Your hate for Apple is completely clogging your logic here.
What implications will it have, exactly? Let's just say what you seem to be implying: that FRAND agreements are worthless once you sue someone. Is that so bad? The patent covenants in the open source world almost always include this kind of term already.
So explain to me why the world will fall apart if everyone gets to ignore FRAND terms when used against parties that are already suing them over patent licenses? That sounds like a good thing to me.
