I can see these 2 CSAM features eventually arriving.Hope you're right, but I'll be staying on iOS 14 until they actually announce that.
- Messages: Given that it is opt-in and affecting only children and teenagers, I think most parents would applaud CSAM warning coming to Messages app.
- Siri and Spotlight: Likewise, CSAM disclaimer on the search results is also non invasive and therefore harmless.
