Look at nuclear technology. Weapons or other wise, super powers and their allies are always paranoid that developing countries may develop nuclear power and all the edge they have in negotiating anything will just go away.
Inventions like things that control vast advances in science and technology are always going to be much about politics and less about altruistic nature of humans to share the inventions with each other.
Fighting bigger wars to prevent small insignificant wars is the common theme these days.
Nuclear technology barriers are more technological than informational. Finding information on how simple nuclear device works wouldn't be that hard I think. Actually creating a device that would work is another matter.
But here nobody actually knows even the ideas behind this - how exactly this thing works. Which sometimes happens too - e.g. see history here about lithium batteries, which was just recently discovered how they work even though they were in use for years. But there nobody knew that, there wasn't some inventor that hides it.
