I’ve only looked at the docs and not implemented it, but my impression was that if they leave the Apple ecosystem they lose access to your app.
I suppose this is similar to any other “Sign in with” option, but it just seems more likely people will ditch Apple before they ditch gmail or Facebook, since they can keep those around pretty easily without using them or paying for them.
For Apple you need to pay money and actively use it to stay in the ecosystem.
Yes, but deletion of a Google account (for a lot of people, the core of their whole internet experience) has way different probability than getting a new, non-apple phone.
