It's not about money. It's not a tradeoff in cost vs quality - it's a tradeoff in development speed. Shipping N separate native versions requires more development time for any given change: you must implement everything (at least every UI) N times, which drastically increases the design & planning & coordination required vs just building and shipping one implementation.
Do you want to move slower to get "native feel", or do you want to ship fast and get N times as much feature dev done? In a competitive race while the new features are flowing, development speed always wins.
Once feature development settles down, polish starts to matter more and the slowdown becomes less important, and then you can refocus.
Doesn't this get thrown out the window now that everyone claims you can be 10x, 50x, 100x more productive with AI? Hell people were claiming you can ask a bunch of AI agents to build a browser from scratch, so surely the dev speed argument no longer applies.
They are not.
A good iOS app is not 1:1 equivalent to what a good Android app would be for the same goal. Treating them as such just gives users a lowest common denominator product.
The productivity comparison must be made between how long it takes to ship a certain amount of stuff.
