They're ahead of the curve in doing this because, in my opinion, they're choosing the path of less resistance. They could go to court, sue, blah blah blah. Instead, they're putting up their own free site exposing their hilarious comedy (that still holds up) to new viewers. Plus, folks like me will still buy the DVD's for extras. And it's free advertising.
