Some Kindle users are angry because Amazon blocked them from their Kindle accounts, thereby blocking them from accessing their already-purchased media. Even if these stories are exaggerated, they once again highlight the caveats that come with DRMed media. You don’t own your content—Amazon does.
Do you think this sort of problem never happened before and it’s an exaggeration? Well, look again at facts because those tell a different story. When Yahoo Music ceased to exist so did the files that people bought. And to get music bought from iTunes liberated from DRM, people had to buy it again.
Facts say that DRM are constantly being used to extort money from customers, and to artificially create scarcity in order to inflate prices. DRM should really be called CRAP as in Cancellation Restriction and Punishment (or Content Restriction Annulment and Protection, if you prefer). Think better and don’t buy CRAP.
