Other browsers were allowed to exist in Windows restriction-free. The DoJ simply took umbrage with MS bundling IE with Windows. The judgment was vacated a year later and IE still ships with Windows and never took over the world. Conversely, the Apple App Store does not allow competitors and is directly the reason you can't buy your app anywhere else. Further, MS never profited directly off of IE whereas a sizeable portion of Apple's profits comes directly from their app store. Also, most of US v Microsoft took place prior to Ballmer coming into power.
