So, by meeting the conditions of the permissive license one is in-fact agreeing to the terms of the license then. It grants anyone the basic copy rights plus the additional rights (hence, the permissive license) only so long as they agree with and remain within the terms of the license.
Make no mistake, I'm not criticizing or questioning the GPL. I'm questioning the idea that one does not have to agree to the license. Agreement being in the form of acting within the stipulated limitations of the license.
