Fairyvision, for example, is a direct lift of the idea of television. The Fairy Kingdom has also "borrowed" the idea of radio though for some reason they couldn't be bothered to rename that. Fairyvision's main gift to the realm it serves has been Roherum and his ideas of news journalism. It's safe to say no serioius journalist has anything to worry about from Roherum's direction.
The Kingdom has been at war with many other worlds in its time and, sometimes amazingly, it wasn't the aggressor. So the realm justifies spying, when it needs to, by insisting it is a useful weapon to ensure they can protect themselves. However the realm's main use of spying will continue to be to purloin ideas for new things and, where it is possible to make a profit out of all this, that's exactly what the Kingdom will do. It is fair to say the Fairy Kingdom has a ruthless streak.
