You know what, never mind
Is clear that GPL is protected by law in Germany and USA, is clear too ( for me at least ) that you can't mix or link non-free software with GPL code ( with lgpl you can ).
What i think is not clear is the server=distribution, for example when kororaa receive a letter from fsf, they ask to kororaa specifically remove the nvidia and ati driver _from the live cd_, wich they do. BUT they never have ask to remove nvidia / ati drivers from gentoo servers ( kororaa depository ), not a single letter, just nothing.
Debian project have a big non-free section in the server, i have never see a letter from fsf asking to remove it because they are braking the GPL.
Almost every big distro ( including suse ) have some non-free kernel modules in the server, i have never see fsf asking to remove those files.
Ok, they have time/money to make a sue, but they have not the time to write a letter ??
