For the example you gave in response to my first reply the GPL license would have permitted them to do as they please. No-one forces a license on you, you choose what license your original code is under. If I would like to prevent my code from being taken and profited from that's also my right. The fact that you can choose what license your code is under is freedom. The non-permissive vs permissive license argument is a moot point, because the very arguments supporting permissive also support the right to use a license such as GPL.
