> I don't know or remember the details of the DMCA, but does it not require the copy protection to be of some reasonable effectiveness (e.g. reasonable cryptography)? No. "Effective" is defined in section 1201 as meaning that the technological measure prevents copying "during the normal course of its operation" -- i.e., the "happy path" of the code prevents unauthorized copying. No matter how trivially the code may be broken, breaking it is a felony. A simple bit of JavaScript embedded in a page that prevents right clicks (to download images) would be an "effective technological measure" under the DMCA. If you put up a web page showing how to get around this with Chrome developer tools, you are "trafficking in circumvention tools" and can be found civilly/criminally liable under the DMCA. Note that there are Library of Congress exceptions for circumventing, but not for trafficking. So you can figure out how to, say, rip DVDs yourself if doing so falls under a LoC exemption. But if you then turn around and publish how to do it, you are still in violation of the DMCA.
