I remember, in the 80's, Xenix was "export restricted", especially libc.a if it had "crypt.o" in it - like the algorithm hadn't been published many years prior to that. Anybody remember the big Toshiba machine-tool controller foorah that supposedly allowed the Soviets make quieter submarine propellers?
Does anybody think that our enemies-du-jour (and our friends, too) aren't reading all our science journals and buying samples of all manner of products for reverse engineering? Or for that matter, does anybody really think that we aren't doing the exact same thing, all over the world?
Lists like these are like "the seven words you can't say on television" - just a dare for somebody to do it.
