I don't disagree. Sorry, I didn't mean to imply you were up to no good. Netflix does have some necessary security concerns, and the article was an interesting look at how they're implemented.

No security is perfect though, and if you lock something down so tight that people can't get what they want from it, they'll find a way to break it. I think Netflix largely succeeds because it makes legitimate uses easy (sitting down and watching a movie) and only impedes the illegitimate uses (burning it to a DVD and selling it on the street).

Music DRM failed largely because its security impeded legitimate uses, e.g. copying your files to a new computer or a new MP3 player.
