The clear solution here is for Patreon to just discontinue in-app memberships and have a message that says "you cannot subscribe using the app, sorry!" It's absolutely reprehensible for Apple to try and take a 30% cut of money that is intended to go straight to creators, but Patreon should not enable them either, even if making that change creates a worse user experience. Apple refuses to even allow app developers to tell their users about the 30%, so the only way to win here is to just cut Apple off at the knees.

They're most likely not allowed to, mastodon.social/@stroughtonsmi…

@miki @simon Wait a minute, didn't I hear recently about them being forced, probably by the EU, to allow letting you purchase on websites? Could ahve sworn there was some kind of recent change to the billing model to allow third-party purchases via websites, though not in-app.
