"The Electronic Frontier Foundation, which opposes DRM, wrote, "Microsoft's Zune will not play protected Windows Media Audio and Video purchased or 'rented' from Napster 2.0, Rhapsody, Yahoo! Unlimited, Movielink, Cinemanow, iTunes, or any other online media service. The Zune will not even play content previously purchased from Microsoft's own MSN Music service. That's right — the media that Microsoft promised would Play For Sure doesn't even play on Microsoft's own device."[53] The EFF calls this "a stark example of DRM under the DMCA giving customers a raw deal."[54]"

"DRM critics say Zune's wireless-transfer policy is restricted and unfair. They claim the Zune is more restrictive than the face value of this common phrase — "three days or three plays whichever comes first."[55][56][57] Because among other things, restrictions are applied to songs for which the recipient owns a paid-for and current Zune Pass;[58] to material that is self-recorded automatically wrapped in 'three-days three-plays' DRM but previously released under Creative Commons licenses or similar licenses with stipulations of unprotected DRM which "does not violate the letter of the CC license but it certainly violates the spirit of the license" said Creative Commons general counsel Mia Garlick;[57][59] to a song that expires in three days even if it has not been played at all;[citation needed] to playing just a portion of a song — within few seconds of a song,[60] or pausing/stopping the song,[56] or the intentional standard of one minute into the song or halfway into the song whichever is shorter[61] — counts as one "play"; and to prevent someone attempting to re-trade a traded song.[61]"

"The Zune is limited to specific versions of Windows,[68][69] and unusable with Mac OS X or GNU/Linux."
