The public domain is our cultural commons and a crucial resource for innovation and access to knowledge. Copyright policy should strive to promote, and not diminish, a robust, accessible public domain.
Copyright law shouldn't interfere with your freedom to truly own your stuff: to repair it, tinker with it, recycle it, use it on any device, lend it, and then give it away (or re-sell it) when you're done.
Copyright policy must be set through a participatory, democratic, and transparent process. It should not be decided through back room deals, secret international agreements, or unilateral attempts to apply national laws extraterritorially.
Copyright law should account for the interests of all creators, not just those backed by traditional copyright industries. YouTube creators, remixers, fan artists and independent musicians (among others) are all part of the community of creators that encourage cultural progress and innovation.
