I find the hysterical arguments against DRM hard to grasp. Accessing various types of IP content is not a human right. There is an abundance of content available in the US which is not DRM'd. It just happens to usually of low quality.
FWIW, the contribution of the artist is only a small cost of the "product" that we consume. There are many other people who work on the teams that create content, and without them it won't reach a mass market (publishers, finance, legal, marketing, logistics).
I find the arguments that somehow DRM is detrimental to the production and distribution of high quality content to be obtuse.
To take another example I am familiar with: software for audio production. Many of the best creators of such software have moved to a very annoying and powerful form of DRM: the use of a physical dongle. Most of them say that without this, they could not be in business, as the pirating of such software is rampant. The DRM doesn't stop it, it merely throws enough roadblocks in the to get a significant percentage of users to pay who otherwise wouldn't.
