There is a reason patents are limited, and that public display of an invention pre-patent can be prior art. The reality is that once ideas are out in the world the creator is no longer in control (which is why we have to create systems of control via laws). “He who receives an idea from me, receives instruction himself without lessening mine; as he who lites his taper at mine, receives light without darkening me.” --Thomas Jefferson
