How GPLv3 addresses the EUCD and DMCA

Draft 3 of GPLv3 should be out Real Soon Now, so I'd like to review some of the topics. I couldn't find a thorough explanation of how GPLv3 will deal with the "anti-circumvention" clauses of the DMCA and it's EU counterpart, the the EUCD (see Article 6), so here's my layperson understanding.

These laws harm society in a number of ways. Some general information can be found on FSFE's EUCD page but here I just want to look at how these laws could cause problems for free software developers and distributors, and what free software licences can do about them.

I see two potential problems:

1. A copyright holder could publish a work and authorise one free software application to access that work, and if a software developer wrote another application to access that same work, the copyright holder could accuse the second developer of copyright infringement for using an unauthorised piece of software to access the copyrighted work.

2. A copyright holder could publish a work and publish a free software program that is authorised for accessing that work, but if a software developer modified that free software program, the copyright holder could accuse that software developer of copyright infringement for using software other than the single authorised version.

Full Story.
