The author's revenge seems to be against his users who opted to used Sign In with Apple. Since they will be the one suffering because they trusted to use the particular app. I can find merit in complaining about apple's restriction in accessing payments. But SignIn with Apple, as a user I will always opt for that given my email won't be available with a third party forever for them to spam or sell. I have integrated SignIn with Apple both in an app and backend. I never felt it was particularly difficult or under-documented.
