It also gives a relatively (/relatively/) equal footing to all apps, short of editor's picks and sponsored results. If you want a podcast app, you will see Apple's own next to something made by a firm of 50 engineers, next to an option made by a 16 year old on a second-hand MacBook Pro. This is in contrast to trying to get on the shelves of Best Buy or CompUSA or Babbages, or anything analog before it.
That relies on your definition of "relative" being relative to garbage. Apple runs Google-style App Store search ads[0] that get pushed above everything else, pre-installs (and sometimes forces) their clients on the user, and has access to entitlements that others do not.
There are a lot of areas for scrutiny. This ruling feels like the can is being kicked further down the road, and with the European regulation coming in hot I expect there to be more debate here. Separating Apple's business practices from their personal policies will probably be where this discussion ends.
