I think Russia is a good answer since there are is probably a lot of software that we don't even know existed from there.

I think a really interesting example is North Korea. There are so many pieces of media that will probably be lost to time because that country is so secretive. Here is a screenshot of North Korea's clone of Clash of Clans. Apparently it's identical but with different skins. I wouldn't be surprised if they also have some state sponsored propaganda hidden in there.
