As others have stated. Its up to consumers to vote with their wallet. If you are appalled by normal retail expenses, there are other options for you. Android has stores you can use. iOS, not even MacOS is the only option I have for what I want.
I choose to pay the Apple Tax for the sake of a closed safe platform. I enjoy having the flexibility to experiment and do what I want on my computer. On my phone, that I carry around everywhere, I choose security first. If that means developers get up and leave, I am fine with that. If you choose to leave because you want an open platform, I'm fine with that too. But don't mess up the only place I can get what I choose.
