It reflects the fact that DRM is a fundamentally incoherent concept -- you can't provide data and all the tools for legitimate users to access it freely and still deny illegitimate uses of the data.
What I meant to say is, that often the real reasons behind using DRM are different from the stated ones (i.e. preventing piracy). And all of those reasons are bad. They usually are some of these:
1. Lack of common sense or just "following the herd" (Lysenkoism).
2. Covering one's incompetence. (Poor sales are blamed on piracy, and DRM is used as a demonstration that they are "doing something about it").
3. Controlling technology progress and direction (like standards poisoning and so on).
Which often reflects the fact that DRM is used for completely other purposes. None of them good.
