DRM is a method by which the distributors can keep charging consumers ad nauseum for access to what they already have paid for. Same goes for media format changes (LP, Cassette, CD, VHS, Beta, DVD, MP3, etc...) We are living an age where you don't purchase anything, you only rent it monthly or weekly.
When you purchase a blender you own it. You can use it as you choose, where, when and how.
Imagine if when you paid for a blender there was a EULA that stated that you actually did not purchase the blender but only a license to use it. Also by "opening this blender you agree to only blend drinks for 4 people or less" (you could purchase a license for a 4 to 8 person blender) and that you could not have any alcoholic product in the blender. And that if you violated any of the EULA that the licenser of the blender could turn off the blender remotely and you have no leave for appeal. That effectively is what the distributors of music want and DRM is the enforcement mechanism.
We have become the ultimate in consumer society, we can now pay money for items we can never own. What's next on the restricted list, cars, shoes, clothing, food... (by purchasing this potato you agree that it will used for its nutritional content only and not for use in advertising or promotion, and built into it is a chip to sense camera lights and explode the potato to prevent such uses)
We need to take back our rights as consumers, avoid DRM protected media, and challenge EULA's at every opportunity (most won't hold up in court anyway). Lets stop purchasing rights and start purchasing products.
