From polishlinux.org: DRM, Vista and your rights

To understand why I am so against DRM, please read this article. One of my favorite points: “Ethical aspect is even more dangerous. In the world of DRM, it turns that we cannot do whatever we want with the legally purchased products (like software, music, videos or text documents). What we can and what we cannot do is decided the provider, not by ourselves. For example, a DRM-protected product can be disabled at any time by the producer if he believes that we violate the terms of the agreement. This means that your collection of ‘protected’ music can be rendered useless (e.g. by decreasing the quality or even deleting the content) in a matter of seconds, without your approval. It that some horrible vision of a sick and evil overlord? Nope. This is an upcoming, terrifying era of DRM.”
