Yes, but the question is how they implemented it. Are there dark patterns, is it all-or-nothing, etc.?
Also, with iCloud being at the heart of Apple's ecosystem, a simple bug may very well cause accidental sharing of sensitive data. Even if that never happens, it does not make me sleep better.
Apple’s apps make it pretty clear when something is local and when something is in iCloud. Even for iCloud users, it’s usually an explicit choice per file or object. Photos is the notable exception.
I’m pretty sure there’s also a very-much-not-fine-print notice about iCloud Photos when you set up a device, and you can easily turn iCloud Photos off. The only part missing is that you can’t enable iCloud Photos but choose, per photo, whether to sync the photo.
It does - there’s a message with a red dot badging in your settings that you can’t dismiss. Clicking it takes you to a nag message to log into iCloud. Still, nowhere near the blatantly insecure and anticompetitive dark patterns that Microsoft uses
