If I remember correctly the Hey! case [1] set a precedent for preventing the blockage from the app store. The argument there was that Hey was an existing business and as long as their app didnāt push the sale of their own subscription, the app could stay. Much like Netflix.
Iām new and naive here, but the way I see it Damus hasnāt pushed/promote the sale of anything, being the āconsumer appā of an āexisting businessā. And as far as zaps goes, you are linking to outside wallets, in which case, even if you need to remove the links, hopefully you could still point users to an online page/PWA with instructions (not ideal but would preserve the consumer nature of the argument)
In the end I hope you can find a solution, as Iām rooting for the future of #nostr and this app.
