> People pay the mafia protection money because it's cheaper than fighting the mob and it makes the mob go away for awhile, and in the long run, we're all dead. Most mafia-like entities don't have an inexorable existential drive to take it all, they just charge what the market will bear.

If I had to guess, the Mafia will have professional economists on payroll telling the bosses about the Laffer curve and emigration.

But in this context, Apple's clearly on the low end of the Laffer curve* because they don't need a million apps, so who cares if the store fees are 15% or 85%, the supply is still there?**; while for emigration, being the least bad of the Apple/Google duopoly is all that is necessary.

* if you take literally that the App store fee is the "Apple tax"

** Answer: Judges in market abuse/monopoly cases because Apple is not actually sovereign; on paper neither is the Mafia, but this is where "monopoly on violence" is a useful definition of a state, in that where anything like the Mafia can exist, the state is de facto not sovereign no matter what it says on paper.
