You miss the point. Spike Lee's argument is that he never employed the artist, even though his film company ultimately decided on the agent who promoted the film.
If he complains about piracy, all we have to do now is state on twitter:
"I Never Heard Of This Spike Lee,If He Has A Beef It's Not With Me.I Did Not Buy Him,Do Not Know Him.Cheap Trick Writing To Me.YO"
Looks like, to me, that unless Lee backs down, he'll be being mocked for quite some time to come :-)
