So Apple pinky-promises they will record everything you do at home and they won't use it? In any way? I find this really hard to believe. Apple is into ads now, so would you let Google/Meta see and listen inside your home all day? Nope.
Conspiracy theories are easy. Now go prove that Apple is lying. They have so much to lose it makes no sense for them to lie.
The point is that they don't have to pinky promise. It's as if you said yubikey pinky promises it won't share your private key.
I think it's actually a very good approach. Obviously depends on actual implementation details, but the premise is good.
