What are you even on about now?
Musk is upset Apple isn't advertising on the platform. They're allowed to do that you know?
Apple are very heavy handed with developers. The 30% is one side, another is the inability to choose to use your own payment platform. The recent rulings and app removals ( we have a few ) have to do with forcing app transactions to go through in app purchases so that Apple can get its cut.
Here's an example. We've had app/apps rejected because one of the tabs or menu items go to that companies website. On their website, they appeal for donations or do transactions. This was blocked. The company had to add a custom style that when the app called their webpage, it did not bring up the financial footers or others. And yes, this was a basic redirect to a browser for that particular call, the apps are fully native and perform other functions, this was just so that the client could still share/display their website as well.
