Let's be clear about this: this settlement means that Apple is offering developers less than what they believe they would be forced to provide by law. There is never any other business logic behind these settlements. This is just another brick on the "benevolent monopoly" road.
To me, Apple losing the App Store appears completely inevitable; and Apple is willing to throw $100 million at a last-ditch effort to keep the status quo.
And if we're lucky and devs are smart, we'll have developers publicly mock those checks from Apple's fund because that was money that Apple took from them with the revenue split and is giving back a fraction of, how generous.
It's like when people get excited about tax refunds from the IRS. Super exciting, until you realize it was excess money taken from you to begin with.
