"Freedom" to restrict and control others and threaten people with legal
sanctions is NOT freedom. It is oppression.
If you make a MP3 or other digital file you are certainly should be allowed
to encrypt it in any manner they see fit and be allowed to sell it in any
manner they see fit. But that is not what DRM does and that is not how it
DRM, according to the laws of reality and the universe*, is a fundamentally
flawed concept. (*aka math). To play back encrypted media it must be
decrypted. And in order to decrypt it you must have the keys necessary to
decrypt it. So on every DRM using piece of hardware and software out there
exists the means to decrypt it and "pirate" anything that is used with that
software. This is why nobody has created a DRM scheme that actually works
or that is secure in any manner.
Since the goal of DRM is to restrict the users and prevent them from
copying the data then you cannot rely on encryption to prevent that. Your
giving them the media, the keys, the software, and the hardware necessary
to copy your data. The only way you can prevent them from violating the DRM
is just by making sure that they do not know how the DRM works, and if they
do know how then make sure that they cannot tell anybody else how it works.
So how DRM really works is through a combination of legal threats,
blackmail, and pure obfuscation. Without the threat of USA government
behind DRM it would be meaningless and a joke.
That is if you do not obey the DRM requirements they will sue you and if
you do not obey and keep fighting them to the end they eventually will send
armed men into your house, take you away from everything you ever achieved
and loved, and throw you into a cage.
THAT is DRM. That is how technologically enforcemed DRM really works. To
even bring up this "freedom" in that context is a complete nonsense and is
actually somewhat insulting.
