I understand, I was inferring some blame on Apple's part from your commentary -- as though they were denying you a living from your app. Anyway, thanks for the discussion. Probably shouldn't necro this thread any more than I have :)
I think this is only another reason to dislike them. Google created the PWA as a way to encapsulate the market on their terms. As my other comments will belie me, I do not disapprove of this behaviour necessarily -- Apple do it too -- but they have the polar opposite attitude to my privacy and data protection.
I think perhaps your business model isn't as solid as you might think. Producing an app is not a free pass to live on the revenue, and the market capture is an important part.
I'm not an app developer, I'm in the music industry (day job in IT infra), but it seems to me there are some people projecting their bad business sense onto Apple. As per my other comment in this thread, and the reply someone made for me, the commission drops on subscription based apps, could you not use a subscription, rather than your pay-per-use system (which sounds like a creative workaround, kudos) and then you'll get the benefit of the tax rolloff.
Trying to make your own way in this world is damn hard work, and if a business model falls apart because one needs to "pay taxes," Apple will not be the biggest problem for very long. I'm sure most here would agree that it stinks that Apple are demanding a 30% tax whilst paying ~0% to the U.S. Government, but that is the way of things for now.
Could you elaborate on this a little? I understand that Apple only takes 30% the first year and then they drop their commission to 15%. Is the commission on the purchase price of the app what makes it too expensive, or is it too great a cut out of your in app revenue?
Apple gear is no longer as comparatively expensive as it used to be -- they aren't ripping you off, they have put a lot of work into delivering different 'gear' to what's available in the rest of the market. Shed a tear for people who buy HP and need a new laptop every year or two. I'm typing this on a 7-year old MacBook Pro, which works better than the day I bought it.
Hosting an app marketplace is not a free endeavour either. They host infrastructure to facilitate all of this, and they review app code in an attempt to prevent malware being distributed by underhanded developers. Maybe they could vary the price based on the use case, but why should they? No one is compelled to publish on the App Store, why complicate their business model to give themselves more work for less money.
