Fair enough, the real rights owner may have uploaded the books and videos themselves. I just think there's some irony here that Hotfile suddenly cares about copyright.
I was questioning the assumption that because they use the law this way they are necessarily bothered one way or the other about the laws and regulations as they apply in contexts other than this one.
Behind WB's ham-fisted tactics may well be conflict of interests: if WB are to distribute multimedia themselves, they sure would consider Hotfile competitors and want to slow them down.
