I have very little sympathy for a man who swindles his way into a company under false pretense.
It may well be that he is right, and I would hardly be surprised that MS stole some tech, but I cannot condone the way he went about obtaining "proof".
I wonder if his "evidence" is receivable in court.

The analogy made me laugh, because any David who tries to take on three Goliaths has too much ambition for his own good. (And is in for a squishing.)
