The reason you can’t find a commercial vendor that will directly ship something to bypass the DRM is because it also says “No person shall manufacture, import, offer to the public, provide, or otherwise traffic in any technology, product, service, device, component, or part thereof, that is primarily designed or produced for the purpose of circumventing a technological measure that effectively controls access to a work protected under this title”

This is also why for a while the t-shirts with the dvd decss key were popular among nerds, because they are illegal.

Are you saying this is incorrect?

> The 2021 exemptions, issued in October 2021, are for:[15]

> Motion pictures (including television shows and videos), as defined in 17 U.S.C. 101, where circumvention is undertaken solely in order to make use of short portions of the motion pictures for the purpose of criticism or comment, for supervised educational purposes, to accommodate for accessibility for disabled students in educational institutions, for preservation of the motion picture by a library, archive, or museum, or for research purposes at educational institutions;

And that exemption only adds cases in which stripping DRM from a DVD becomes legal. It's still generally illegal, and most people using makemkv are likely using it illegally.

I'm not sure this has ever been tested in court, though. And even the DMCA itself does provide for a rather clunky system of "exemptions" to the no-circumvention provision.
