That's an important distinction, but yes, it's irrelevant here. If Apple offered on-device, privacy-preserving, not-uploaded facial recognition, I wouldn't be inherently opposed to it. There's no way Facebook wouldn't feed that data right into their own Eye of Sauron.

Same with Logitech Circle doorbells that tell you which of your friends or family is at the front door, using local computing. That's a great feature. I wouldn't use a Ring camera that was shipping the data back to Amazon and any number of police departments.
