> "Out of the blue, one day they said you have to add in-app purchase to stay in the App Store. They stumbled upon something in the app that mentioned there were paid plans, they went to the website and saw there was a subscription you could purchase, and then turned around and demanded we add IAP. There's nothing you can say to that. They are judge, jury, and executioner on their platform, and you can take it or leave it. You can't get any sort of fair hearing to determine whether it's justifiable or not justifiable, anything they say goes. We simply complied in order to save our business."
Yes, as I said, ideally Apple would allow other forms of payment alongside IAP, but that's not even the issue here. The issue here, as I said, was that ProtonMail was trying to avoid implementing IAP at all.
