SellingDigitalMusicwithoutCopy-protectionMakesSense

A. Itwasuncharacteristicallylow-keyfortheindustry’sgreatestshowman.ButtheessaypublishedthisweekbySteveJobs,thebossofApple,onhisfirm’swebsiteundertheunassumingtitle“ThoughtsonMusic”hasnonethelessprovokedavigorousdebateaboutthefutureofdigitalmusic,whichAppledominateswithitsiPodmusic-playerandiTunesmusic-store.Atissueis“digitalrightsmanagement”(DRM)—thetechnologyguardingdownloadedmusicagainsttheft.SincethereisnocommonstandardforDRM,italsohastheside-effectthatsongspurchasedforonetypeofmusic-playermaynotworkonanother.Apple’sDRMsystem,calledFairPlay,isthemostwidespread.SoitcameasasurprisewhenMr.JobscalledforDRMfordigitalmusictobeabolished.

B. ThisisachangeoftackforApple.IthascomeunderfirefromEuropeanregulatorswhoclaimthatitsrefusaltolicenseFairPlaytootherfirmshas“lockedin”customers.SincemusicfromtheiTunesstorecannotbeplayedonnon-iPodmusic-players(atleastnotwithoutalotoffiddling),anyiTunesbuyerwillbedeterredfromswitchingtoadevicemadebyarivalfirm,suchasSonyorMicrosoft.WhenFrenchlawmakersdraftedabilllastyearcompellingAppletoopenupFairPlaytorivals,thecompanywarnedof“state-sponsoredpiracy”.OnlyDRM,itimplied,couldkeepthepiratesatbay.

C. ThisweekMr.JobsgaveanotherexplanationforhisformerdefenceofDRM:therecordcompaniesmadehimdoit.TheywouldmaketheirmusicavailabletotheiTunesstoreonlyifAppleagreedtoprotectitusingDRM.TheycanstillwithdrawtheircataloguesiftheDRMsystemiscompromised.ApplecannotlicenseFairPlaytoothers,saysMrJobs,becauseitwoulddependonthemtoproducesecurityfixespromptly.AllDRMdoesisrestrictconsumerchoiceandprovideabarriertoentry,saysMrJobs;withoutittherewouldbefarmorestoresandplayers,andfarmoreinnovation.So,hesuggests,whynotdoawaywithDRMandsellmusicunprotected?“Thisisclearlythebestalternativeforconsumers,”hedeclares,“andApplewouldembraceitinaheartbeat.”

D. Whythesuddenchangeofheart?MrJobsseemschieflyconcernedwithgettingEurope’sregulatorsoffhisback.RatherthancomplainingtoAppleaboutitsuseofDRM,hesuggests,“thoseunhappywiththecurrentsituationshouldredirecttheirenergiestowardspersuadingthemusiccompaniestoselltheirmusicDRM-free.”Twoandahalfofthefourbigrecordcompanies,hehelpfullypointsout,areEuropean-owned.MrJobsalsohopestopainthimselfasaconsumerchampion.AppleresentsaccusationsthatithasbecometheMicrosoftofdigitalmusic.

E. Applecanaffordtoembraceopencompetitioninmusicplayersandonlinestores.Consumerswouldgravitatetothebestplayerandthebeststore,andatthemomentthatstillmeansApple’s.MrJobsisevidentlyunfazedbyrivalstotheiPod.Sinceonly3%ofthemusicinatypicaliTuneslibraryisprotected,mostofitcanalreadybeusedonotherplayerstoday,henotes.(AndeventheprotectedtrackscanbeburnedontoaCDandthenre-ripped.)SoApple’sdominanceevidentlydependsfarmoreonbrandingandeaseofusethanDRM-related“lockin”.
