Another Reason Why DRM Is Bad -- For Publishers

As a way of fighting unauthorized sharing of digital files, DRM is particularly stupid. It not only doesn't work -- DRM is always broken, and DRM-less versions quickly produced -- it also makes the official versions less valuable than the pirated ones, since they are less convenient to use in multiple ways. As a result, DRM actually makes piracy more attractive, which is probably why most of the music industry eventually decided to drop it.
