GigaOM - Apple finally responded on Thursday to the Justice Department’s lawsuit against it and several of the Big Six book publishers — for allegedly colluding to keep e-book prices high — by releasing a statement saying it did nothing wrong. The company says its agreement with publishers actually helped break Amazon’s “monopolistic grip” on the market, and that it always lets the companies that supply it with things like apps or books set their own prices. But wait: didn’t Apple more or less control the market for digital music in the early days of iTunes, and dictate prices to the major record labels in order to keep prices low? It sure did. In other words, it behaved more or less the same way towards the music business as it accuses Amazon of behaving towards the publishing industry.
