Viacom Sue YouTube for $1bn

It seems like Viacom are set to try and prove a point about You Tube.

Although spending millions on lawyers seems counter productive. Why instead do they not just partner with Youtube to enable them to distribute their content legally and take a cut of the ad revenue. I don't think Viacom are going to get much more than a hefty legal bill by pursuing piracy laws which were developed for a completely different world and are gradually becoming less relevant and almost impossible to enforce.
