if zapplepay works fine on damus, and using small-sums trusted MWC setups with services like alby (which is ok imo) is also fine, the issue with damus zapping is pretty much just an issue of how the UI looks
how can damus create a UI that doesn't look like a payment to the bureaucrats that review apps on the app store?
currently zapplepay supports only a fixed sum, but they can easily make a different sum for each different emoji (i.e: 🤙=21, ❤️=69, 🍑=420), for example
at the end of day it's an arms race, and every tactic is legit, just like every tactic the authority uses is legit in their strategy
