I doubt that George would go out of his way to target one actor, suffering from and doing a lot to raise money into findiing a cure for Prostate Cancer, just because of some yet to be proved theory that he was leaking plot details to the press.
That would be like saying Anthony Daniels and Kenny Baker don't get along.
Perhaps if George looked under the sofa cushions of his tiny $100,000,000 ranch he might find a bit of lose change he could send big Dave.
