It’s illegal to circumvent copy protection under the DMCA (something I wholeheartedly disagree with), but it’s not illegal to make something that can be used to circumvent copy protection.
It is explicitly illegal to produce any thing whose purpose it is to circumvent DRM:
(1) No person shall manufacture, import, offer to the public, provide, or otherwise traffic in any technology, product, service, device, component, or part thereof, that—
(A) is primarily designed or produced for the purpose of circumventing protection afforded by a technological measure that effectively protects a right of a copyright owner under this title in a work or a portion thereof;
I’m telling you, that law is mental.
In fact, there are exemptions to that provision and one of them states that circumventing copy protection in order to play a video game using assistive technologies is legal.
Could you point that specific exception in the law? I can’t find it.
