There's only a handful of sources for the services revenue which is growing like crazy, I wonder if they've been able to negotiate a higher ad revenue cut with Google which was revealed to be 36% in Google's antitrust trial, leaving a lot of money on the table.
It definitely looks like they've been able to stall the effect of rulings allowing apps to use third party payments. But earlier this week the courts reversed a stay of December's injunction that limits Apple to a very small fee, in their arguments against the stay Epic claimed developers were hesitant to use 3rd party payments until they knew what the final cost would be and that reversing the stay would mitigate their fears so it will be interesting to see what happens next quarter.
It's worth considering (IMO, anyway) that users don't want to use apps that use third party billing, too. That's my own preference, I avoid them and look for something that lets me pay via the App Store instead. In the cases where I can't do that (Disney, Netflix), I just leave a bad review and send feedback on their website asking to pay in the app.
