alt Hacker NewsNote that there is the following exception to dmca circumvention provision:
"Computer programs and video games distributed in formats that have become obsolete and that require the original media or hardware as a condition of access, when circumvention is accomplished for the purpose of preservation or archival reproduction of published digital works by a library or archive. A format shall be considered obsolete if the machine or system necessary to render perceptible a work stored in that format is no longer manufactured or is no longer reasonably available in the commercial marketplace."
Some people find this confusing. Section 1201 of the DMCA has two parts. One part bans circumventing DRM, and the other part bans distributing devices that can circumvent DRM. The Section 1201 exemptions published by the Copyright Office only apply to the first part, not the second. I imagine it works this way because the companies lobbying for the DMCA to be passed didn't want to make it legal to sell or distribute circumvention devices as long as someone has a legal right to break the DRM, as that would defeat the purpose of the law.
