I'm not sure if there's anything you can do, perhaps you have to use the standard terms that the copyright monopoly puts out (or perhaps you disagree with my interpretation
), but I object to the term "Digital Rights Management". Usage of the word "Rights" has a positive connotation and implies that the assumption is that the copyright industry is merely protecting what they feel are their rights. Instead, "Restrictions" is a more accurate term both in the context of what DRM systems actually do and in what the copyright industry is, by their own statements and admissions, actually seeking to accomplish.
Usage of the term "Management", in either case, also lends a more positive implication than I feel is appropriate. As "Digital Rights Management", the implication is that the copyright industry is managing the privileges available to consumers and lessens the impact of the concept that consumers have only purchased a license and actually don't have any standard property rights. As "Digital Restrictions Management", the implication is that restrictions are being managed and so they're not as bad as they could be, which again lessens the impact of what DRM actually does. I'm not sure what would be most appropriate, but at least a neutral word like "Mechanisms" or "Methods".
