Is there a "Natural Law" that enforces to supply "equivalent" "source
code"  and "machine code" for copy - left licensed software ?

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" :

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 .
