I have made it a point to avoid iCloud, and occasionally I will find apps that have been enabled to sync with iCloud that were previously disabled. I am the proud owner of a zero kilobyte iCloud account. (And the proud owner of a brand new GrapheneOS device. See you, Apple!)
I’m curious as to how this manifests when advanced security is enabled. Advanced security on iCloud is supposed to make photos and many other services e2ee.
