Welcome. This is a good question which raises a lot of issues.
The problems I have with the technology mentioned in this article is that it seems to place a financial burden on the consumer, that it seems to block out ordinary "fair use" of copyrighted material (i.e. copying it for personal use), and that it seems fairly easy for people who want to duplicate the material for illegal purposes to get around it. Hence, I see added costs and inconvenience for very little return.
Not that I have a good solution for the very real problem of copyright violation. Perhaps the only thing to do is to crack down on it at the point at which this material is sold illegally. This is extremely hard to do, of course. I've heard stories of illegal copies of movies being sold on the streets
before the film is released in theaters. If the pirates are that sophisticated, simply adding technology that makes it a little more difficult to copy digital information seems pretty ineffective.
