iPod Firmare Update Blocks Use of Songs from RealNetworks' Online Music Store

Back in Augest, I believe, RealNetworks created a software program called "Harmony" which let users put music from RealNetworks' online music store on their Apple iPod. Well an article over at News.com says that a recent update to the iPods firmware released by Apple brakes compatibiltiy of the Harmony software. Here's the kicker: Apple did not mention anything about Harmony in the release notes for the firmware, imagine all the people who used their iPods' with RealNetworks' online music store and now it just stopped working?
