Query: Warner Bros. and Ultraviolet stupidity.

When will the Studios learn to stop trying to screw their customers! I had preordered this movie in October, I received it last month and learned about the idiotic attempt to control their users that is Ultraviolet, and steal their choice of formats. luckily I hadn't opened it yet, and have since returned it to Amazon.I will never again buy anything associated with Ultraviolet, I already use iTunes, its simple, and it works! WB stop your stupidity or you will just drive everyone to download movies, and you will lose!Amazon you need to learn to stand up for your customers like Apple does, and stop supporting the studios stupid ideas.
