This leaves in place the bulk of the ruling favoring Apple, but also the elimination of the anti-steerage rules that Epic successfully challenged (sort of, the trial judge mostly did that on her own).
So, to summarize, the relevant market is this dispute was the mobile game market (not an iPhone-specific market like Epic wanted), Apple does not have a monopoly in that market, and Apple doesn’t need to charge less in the App Store or for in-app purchases. But, due to California law, Apple cannot prevent developers from informing consumers that lower prices are available outside of the app.
