Just as a reminder, Digital Rights Management was introduced to prevent people from using digital content in ways that its producer didn't approve of. In many instances this means preventing unauthorized copying of MP3s or software.
In reality however, DRM simply amounts to an annoyance for legitimate customers, while those people who weren't planning to buy but pirate, have plenty of ways to hack or crack the copy protection schemes. Luckily more content providers have started to realize this. But not all of them.
