This arises from the fact that the electromagnetic spectrum too has been treated as property since the second quarter of the 20th century. That was said to be technically necessary as a result of technical problems with interference that are no longer relevant in the world of intelligent devices. The single greatest free software problem in the 21st century is how to return the electromagnetic spectrum to use by sharing rather than use-by-propertization. Here again, as you will notice, free software itself, free executable software, has a major role to play.
