They did not scan everything. Only suspected ones, this expands scope to everyone by default. But this is still improvement. We might see followup as added E2EE services which was not possible before.

So are they only scanning things you specifically upload to iCloud, aka if you disable iCloud and photo syncing you are fine.

Or does that include ancillary data like images in iMessage chats (even if you have iCloud data basically shut off)

I read the scans were done on device but prior to upload. Just unclear what that really means to me.
