The main reason to worry about a foreign government knowing too much about you is if they might use it against you. When they're far away, that's extremely unlikely, however if you travel there, it suddenly becomes a real possibility. Bad things have happened to Americans who visited Iran and North Korea, for instance. However, if you don't plan to visit countries like this, this isn't something you should probably worry about. I have no plans to visit either of those countries until they have completely different governments, so I really don't care if they don't like me.
