Every developers knows ahead of time that Apple's integrative fee for [software licenses/developer support/hosting services/customer discovery/residual goodwill/merchant costs] is 30%. Your direct competitors probably aren't getting out of a comparable fee either, so it's not like the fee is making you uniquely uncompetitive. If you can't afford to maintain an app from 70% of the top line revenue perhaps the price of your app is too low?
For decades, developers were lucky to see 50% of the retail price. More likely they'd see 20-40% after the retailer and distributor took their cut. And then this 20-40% has to pay some very expensive licenses for software development tools (we forget that these tools used to be commercial software) as well as licence fees for any toolkits you might have used (such as Unreal Engine).
