Information wants to be free

The phrase is a simple observation, like saying “a compass wants to point north”. Information intrinsically has a tendency to spread. Controlling information, bottling it up and keeping it limited, is difficult. There’s a bit of a poetic turn in saying “wants”, since of course information has no agency. The underlying truth is really a statement about human nature; people tend to share information

Also along these lines: “There are no secrets, only information you don’t yet have.”
