DRM == control users != anti-piracy (Score 1)

As mentioned by others, any content that is meant to be viewed or heard can never be secure to the point that piracy can't happen. It would be naive to think that Hollywood isn't aware of that, what they want to control are the channels by which a consumer pays for the content. If you can get the consummer to pay for the content in several different ways without allowing them to reuse content across formats and viewing mediums, then you stand to make more money.
