Fukase's restrictions aren't too different to other Vocaloids, to the point where it was an issue on if they should even be mentioned.

In regards to Miku, you actually have to also seek permission, however, CFM made it easier to do so by making the licensing more open and providing methods to get permission easy. IA actually I believe has the most open licensing of any Vocaloid.
