After a careful review of today's events, I can say with some confidence that Apple will be forced to accept some level of competition.
Precisely what is that will be is strictly up to the Judge, & she gave NO direct hints of what it could be.
Here ruling is expected no later than mid-August, but I think it could occur within 30-45 days.
She appeared to be well-prepared for over-seeing the trial, & did a good job of beating-up Cook today on Apple's lack of competition, & thus NOT having any incentive to improve.
IMO, "App Discovery" App Stores would be a good first step !
Such app stores would compete head-on with Apple in App Discovery, & (naturally) get a cut of Apple's action for ALL transactions that they are responsible for (a 1/3 cut would be a good starting point).
In a perfect world, Apple would set its cut in the Mac App Store @ 10% for ALL financial transactions, AND @ 15% in the iOS App Store for ALL financial transactions.
That, combined, with third-party "App Discovery" App Stores, would, IMO, be ideal for both End Users & App Devs !
And, very-likely eliminate the need for New Law, which is almost certainly coming if Apple isn't pro-active !
