thanks for bringing up this to eyes and ears. it is almost shittily surprising to see nobody responded to this.
i think, this was in place, because of the hegemony of globalized financial institution and sphere, which would react the delinked nation states if they delink from the institution to isolate from the complex global economic and financial crisis & "exogenous innovation stimuli" to solve the crisis itself, which in first place came in to exisitence by the very practice of the policies established and shoved by these globalized trans national institutions and establishments.
yes ip-address based restriction is condemnable, and it clearly shows, the shitty structure of internet, which is used as an instrument of control as a id.
i dont know what to say about justification. as far as availability & accessibility is concerned that forms the roots of free software and other allied open technologies, this is grave. what good is free software and internet, if they do not enable the creations to reach the far depths of internet in reality. Not supporting a friend for just she is not in compliance with your ideology is in-humane. why the embargo on immaterial resources ? The author of the free software does not have imagined any such thing while writing it, or atleast have imagined about how it would be useful for a student accessing and using it in hard to reach places.
this happens, because end of the day, the present systems in place, see all creations as commodity, and thus classifies as "exportable" product, through a different medium called internet, which has to follow the policies of international fin. inst. & est. This in effect might be viewed as "protectionism or conservatism" by such systems against who do not want to bend as the master orders.
personally, i dislike the national states of N.K and Cuba for some political reasons within me. Nevertheless, this proves how crappy the whole scenario is.
