Every business that is being shaken down should just quit right? Like the bakery paying protection money to the local mob they may lose 30% every month but hey they still made 70% right?
No. This is why we have competition law. This is why there are movements all over the world (South Korea, The EU, specific states in America) all working to undo Apples anti-competitive one-store-only policy.
And thank goodness, we're winning for consumers everywhere.
EDIT:// Also I did want to speak more about this. You asked about us still releasing things on iOS. The 30% cut from Apple did actually make us stop supporting some older apps on iOS while we continued to support them on other platforms (Windows and macOS). That is simply because that 30% cut is the equivalent of several employees.
We also transitioned one app to be "free" but once launched asked you to login to an account which is paid for outside of the app. The problem is due to Apples rules we're not allowed to tell users any website address or have any buttons that leads them out of the app so that they can pay for the subscription the app requires on our own website. Similar to how Netflix can't do that either.
The double standard that Apple has here is quite frustrating because if we sold a physical good like Amazon or UberEats we don't have to give Apple a 30% cut. They get nothing and we can use our own payment system in the app, for instance from Stripe our preferred card processor. But because we provide a digital good somehow it's worth less than a physical good in Apples eyes. This is really ridiculous when we are still paying employees and paying for physical resources to backup what we deliver to consumers (we pay for servers and we have to buy software and computers to actually make the software we sell digitally).
So ya know, there's a lot going on here, the 30% cut is for us terrible. It's higher than sales tax and card processing fees combined and Apple provides very little value to us in exchange for that which is why as I said for some of our apps we abandoned them on the iOS platform and for other apps moved to subscriptions that are started from our own website.
