The link at the bottom of the www.memestreams.net page entitled "TI-83 Plus OS Signing Key Cracked - ticalc.org."

[ED: The text "TI-83 Plus OS Signing Key Cracked - ticalc.org" was originally a hyperlink that TI claims I cannot make.]

Texas Instruments Incorporated ("TI") owns the copyright in the TI-83 Plus operating system software. The TI-83 Plus operating system uses encryption to effectively control access to the operating system code and to protect its rights as a copyright owner in that code. Any unauthorized use of these files is strictly prohibited.

Am I missing something?

Key 0004 is a signing key. It does not (to my knowledge) protect any copyrighted files. This isn't like disabling the content scrambling on DVDs. All you can do with this key is impersonate legitimate TI software - i.e. run a homebrew os on the TI-83+. I don't see how key 0004 is copyright protection in the first place, and I don't understand how you can bring up the DMCA at all.

If anything, cracking and using another person's signing key might be rightfully considered forgery. However, this would seem to apply only if you are literally pretending to be TI in the distribution of TI-83+ operating systems.

All people are doing is trying to use the hardware that they legally purchased and own. You don't sign any sort of a license agreement when purchasing a graphing calculator.
