There is some interesting information here, but I am concerned about the terminology. For example: "Unlike some Washington advocacy groups that are predictably anti-copyright, ...." -- who would that be? After all, even, say, Richard Stallman could reasonably be described as "pro-copyright". I'm not sure how much trust I want to place in an article when the author gives evidence of not quite understanding its primary topic.
I would think that the statements regarding its support of the RIAA suing filesharers and Heritage fellow Edwin Meese comparing using Kazaa to "shoplifting DVDs" would indicate that Heritage members have traditionally taken views that side with the RIAA and MPAA.
Well, yes, but the RIAA and MPAA aren't "pro-copyright". Nor are those who oppose them "anti-copyright".
