Digital Restrictions Management

Digital restrictions management, originally known as digital rights management, restricts digital freedom. It can be used for semi-legitimate purposes such as protecting MP3 files as M4P files that cannot be copied to other users' iPods. It can also be used by digital libraries to intentionally make the software less efficient to force people to buy more expensive Kindle tablets. Digital restrictions management, especially in this case, is completely unethical and has been shown to encourage piracy. There are many organizations such as the Free Software Foundation that fight this practice.
