Zune’s Big Innovation: Viral DRM
Microsoft's Zune player supports wireless sharing of media, with a catch: anything you share gets DRMed with a three plays or three days limit. This is phenomenally stupid. First, it violates the copyright of any content licensed under a Creative Commons license, since those licenses prohibit DRM which interferes with permitted uses (including, for example, redistribution). Second, it permits (limited) infringement on the copyright of content not licensed for redistribution at all. Microsoft might have the RIAA's approval for the latter, but they certainly do not have the Creative Commons' approval for the former.
Give Zune a pass. Say no to viral DRM.
