That's not Apples problem.
By the way, I believe the App Store is slowly dying.
I know literally no-one who bought a paid app, maybe a really small In-App purchase.
I cannot recall wether Apple has bragged about the payouts to devs recently.
Considering the hardware lineup, with limited Xcode support, I know lots of people who simply stopped developing.
Also, GDPR, Terms and Conditions, etc. play a role for small devs.
How is this any different from day one? Big development shops always make the most money on the App Store. (Apple always leaves this detail out when they boast about how much money "devs" are making.)
