Many types of technical information are also protected. Not in the "classified" sense but in the sense that there are legal controls around exporting it to certain nations. Especially nations under UN sanctions.
Fair enough. Just offering an alternative/oldskool reading of this situation (this thread started out surprisingly negative against a mindset that used to be common among hackers). Laws on sharing information can sometimes be at odds with the hacker spirit of freeing information, for instance in the case of Aaron Swartz.
