> Why should users pay full bundled iOS tax that supports security updates,

I don't think I've ever seen someone express the expectation that Apple's App Store fees are for the purpose of supporting iOS development and maintenance. Mostly I've seen and heard the expectation that those fees are connected to running the App Store itself (payment processing, hosting, app review, etc.) and beyond that, vague profiteering. iOS itself isn't a subscription service, and Apple seems quite happy to sell you devices even if you don't spend money in the App Store. So you seem to be stretching a bit by attributing those fees to iOS maintenance and then turning around to say that unsupported iOS versions should get a discount on the fees for any services that still work.
