Perhaps, if only the segment of the population forced to use a browser that didn't support PWAs for over a decade. I can see why they would forget about websites over a long enough period of time.
Hell, Jobs originally wanted there to be no iPhone SDK, and for everyone to create webapps. Man, that would have been a better world. Initially it would have sucked, but the mobile web platform would have improved so much faster, and APIs for doing native-y things would have been complete and useful 15 years ago.
I subscribe to a bunch of Patreons, and most of them are videos (which I can view on a website) or they're downloadable assets I use my PC for accessing anyways, wouldn't make sense on mobile no matter app or website.
I’m not sure why Patreon couldn’t replace the “subscribe” button with a “wishlist” button within the iOS app. They could add a link that opens your wishlist in the browser too. It turns what should be 1 click into 3, but it seems far more sensible than accepting the 30% fee.
And if it is true that they're not allowed to disable payments, I would also love to know what's special about Amazon, Netflix, and Spotify (other than their size) that would allow them to "get away" with the same behavior.
