Even if thats true why the fuck would Ubisoft be happy about losing free promotion? A trailer is basically an ad no matter where its posted

A while back, WB uploaded all of "Batman Beyond: Return of the Joker" to Youtube in several parts, then accidentally took their own videos down. AFAIK, it's still not entirely back up.
