How do you know such things? Make some sense of that for me please, because if this was common knowledge there would be jobs lost.
What you said makes no common sense unless you are claiming a somewhat global conspiracy which would seem very unrealistic.
How do you know such things? Uh, because I am in the business! And you are not!
Of course, you wouldn't believe that either.
So you keep spouting off about what you don't have a clue about....
