Who can "prove" that the supplied "source code" is "different" from the supplied "machine code" ? This is an "Undecidable" problem which is "Turing's Halting Problem" : https://en.wikipedia.org/wiki/Halting_problem in a form to try to prove that two "programs" are equivalent or not ( they pass the same execution points or not ) . This means that , claiming that "copy-left licensed software is more secure than permissive licensed software" is a groundless and incorrect claim . Thank you very much . Mehmet Erol Sanliturk
