The situation is very simple in fact. Somebody just lost the ground and cannot see the difference between the free software authorship, credit for it and property rights no more. He accepts the free license but in a some strange one-way fashion: to get the freedom for himself and to take it away from the others. Just like terrorists do. Setting timebombs and objecting others to disable those bombs is not only the violation of free software license as up to me, but also it spoils the idea of the free software itself. Now I see how great is the idea behind the GPL.
