So it’s our disclaimer that says you can buy a membership - which is required to use the app - outside of the app.
Now I wonder if we should also add a button that send the user directly to our website.

In other words Apple doesn’t really care that we’re instructing users on how to evade their 30% commission.
It only cares that when “content” is “purchased” AND “consumed” inside the app, they get 30% of it.
The original zap feature doesn’t fit that description as the content was not purchased. It was public, zaps were like micro donations. Apple is likely afraid of BTC circumventing their ability to charge fees entirely. An interesting test is to submit a new app, with the old feature enabled but that gives 30% of the BTC to Apple.
