Well as long as he keeps his 1.5 billion and has control he could reduce the other O/S by doing share buybacks and it would lower the O/S while still keeping him in voting control.
He may still retire those 1.5B shares he received upon becoming CEO...he has another agreement stating he has right to purchase 50M restricted @ $0.0001, and options for 70M more (p. 15/23 of quarterly)
