Having a large customer base is not an argument against them being a monopoly. Quite the opposite, it is evidence of it being a monopoly.
> Charging a fee for giving developers a huge market that spends money is not exactly unfair.
It is unfair if they are engaging in anti-competitive practices to prevent competitions from competing.
> What would make it fair? Lowering the fee?
Allowing alternative apps stores to compete against apple's would make it fair, and giving users the option and ability to do this, easily. So, specifically I should be able to install a Steam, or epic app store, on the iphone, without apple having any ability at all to stop me, or take a cut.
> What actual harm is Apple inflicting on the market by their behavior? Developers make less money? That isn't good enough.
Of course it is. If you have a monopoly, then the harm is on the customers of the market. That includes both buyers and sellers. That is how monopolies work.
And also, it is not just developers making less money. Instead, the monopoly place in the market, prevents developers from passing on the savings to the consumer.
So the fee would have to be literally 0%, for me to even accept the idea that consumers aren't harmed by it.
