> iCloud is not end-to-end encrypted Yet. Have you considered that this might be a necessary precursor to making iCloud e2e?
If the goal was to make iCloud e2e, why not release both features at the same time so people can see that they're codependent (in Apple's eyes)? Without any kind of announcment or promise of e2e iCloud, we're just speculating for possible reasons why this might be OK. Might as well guess that this is going to allow Apple to give us free iCloud storage, too, while we're coming up with wishlist features.
Sure. All the statements about why it’s not ok are also just speculation.
> why not release both features at the same time
That’s not how Apple typically works. They release a feature, try to make sure it works as expected and only then release the features that depend on it.
