Recall that when CD copy protection was starting to be deployed, you could negate it with a black marker. The DMCA then made black markers illegal, because it bans "tools which may be used to circumvent copyright" as well as the "circumvention of copy protection measures". (Not that anyone tried to enforce it, but the letter of the law was pretty clear that black markers were then illegal to possess)
The DMCA should be amended or revoked to make these shenanigans no longer enforceable.
No court would ever come to the conclusion that something as mundane as black markers are illegal to possess.
The DMCA is a problem because putting copy protection on (for example) heated seats is a similar level of silliness to outlawing black markers.
That is wrong. It's legal to possess a hammer but illegal to bash someone on the head with one. It was legal to possess a black marker and arguably illegal to use it to circumvent copy protection.
It may fall afoul of the (terribly written, but still law) Section 1201 of the DMCA, if it's arguable that the circumvention provides access to computer software (and I think it is arguable).
I agree that this should be legal, but I'm not nearly as convinced that it is legal currently.
