Has Apple announced that they're making iCloud end-to-end encrypted? It seems like people see the on-device scanning as a road to an "obvious" next step, but I'm not sure that Apple has announced that that's the next step. They might scan your device locally, and mine everything in the cloud for advertising purposes. They haven't said anything to the contrary, and their current terms of service allows it.

I could be missing something, but I did a quick search and all I see is news about them scrapping their once-encrypted backups at the request of the FBI.
