I’ve been an Apple customer for 35 years. Had an Apple account as long as Apple has had such things. A few years ago (specifically, when Apple started retiring 32-bit apps from the App Store) I saw where Apple was going and created a dedicated account for my Apple ID that’s separate from the one I use for my contact for Apple services.
If Apple locked me out of my account today, I’d lose access to 14 years of app purchases on that account. That’s about it? And at some point I started using an alternative ID for some of my purchases, so I’d only lose access to some of them. And of course, I now keep copies of everything backed up, since they could vanish from Apple’s servers at any time.


Apple is the only provider of Apple IDs.
Other yhan that, I’m not sure what gave you the impression I’m dependent on a single provider?
