Understanding how Apple’s FairPlay DRM works helps to answer a lot of questions: why it hasn’t been replaced with an open, interoperable DRM that anyone can use, why Apple isn’t broadly licensing FairPlay, and why the company hasn’t jumped to add DRM-free content from indie artists to iTunes.
This article throws around the idea that an open-standard for DRM is currently not possible, because the concept of interoperable DRM generally makes no sense. It’s an oxymoron. If you are a fan of DRM news, then this is a great read. In-depth, so you should have a coffee ready before starting.
